  • Question 1
    1 / -0

    In an election, two candidates Amit and Bittu contested. Bittu got 60% of the votes. The total votes polled were 8000. How many votes did Amit get?

    Solution

    Total votes polled = 8000

    Bittu got 60% of the votes

    Number of votes Bittu got = 60% of 8000

    We can write it as

    = 8000 × 60/100

    = 4800

    Numberof votes Amit got = 8000 – 4800 = 3200

  • Question 2
    1 / -0

    What is thepercentage of a, e, I, o, u in the English alphabet?

    Solution

    We know that there are 5 vowels in 26 English alphabets

    So the percentage of vowels = (5 × 100)/ 26

    We get

    = 250/13

    = 19 3/13 %

  • Question 3
    1 / -0

    King got 75% marks out of a total of 1000. How many marks did she lose?

    Solution

    Total marks = 1000

    Marks scored by king = 75% of total marks

    Total marks scored by king = 75% of 1000

    We can write it as

    = 1000 × 75/100

    = 750

    So the marks lost by king = 1000 – 750 = 250

  • Question 4
    1 / -0

    In a class of 60 children, 30% are girls. How manyboys are there?

    Solution

    No. of children = 60

    Percentage of girls = 30%

    So total number of girls = 30% of 60

    We can write it as

    = 60 × 30/100

    = 18

    Numberof boys = 60 – 18 = 42

  • Question 5
    1 / -0

    What percent of 24 kg is 1450 gm?

    Solution

    24 kg is 1450 gm

    We know that

    1 kg = 1000 gm

    So we get

    24 kg = 24 × 1000 = 24000 gm

    We can write it as

    = (1450/24000) × 100

    So we get

    = 145/24%

    = 6(1/24)%

  • Question 6
    1 / -0

    Express:3 2/5 as percent

    Solution

    3 2/5 as percent

    We can write it as

    3 2/5 = (3 × 5 + 2)/ 5 = 17/5

    By converting 17/5 as a percent

    = 17/5 × 100

    = 340%

  • Question 7
    1 / -0

    A person saves 10% of his salary every month. If his salary is ₹ 3000, find his expenditure.

    Solution

    Salary = ₹ 3000

    Saving in every month salary = 10% of salary

    So the total savings = 10% of ₹ 3000

    We can write it as

    = 3000 × 10/100

    = ₹ 300

    Totalexpenditure = 3000 – 300 = ₹ 2700

  • Question 8
    1 / -0

    Find 2% of 2 hours 30 min.

    Solution

    2% of 2 hours 30 min

    We know that

    1 hour = 60 minutes

    So we get

    2 hours 30 min = 2 × 60 + 30

    = 120 + 30

    = 150 min

    We can write it as

    = 150 × 2/100

    So we get           

    = 30/10

    = 3 minutes

  • Question 9
    1 / -0

    Express-

    3: 20 as percent


    Solution

    3: 20 as percent

    We can write it as

    = 3/20 × 100

    So we get

    =15%

  • Question 10
    1 / -0

    Sam bought a basket of mangoes containing 100 mangoes. 15% of these were found to be rotten. Of the remaining, 20% got crushed. How many mangoes were in good condition?

    Solution

    Number of mangoes = 100

    So the rotten mangoes = 15% of 100

    We can write it as

    = 100 × 15/100

    = 15

    Remaining mangoes = 100 – 15 = 85

    We know that

    Mangoes crushed = 20% of 85

    We can write it as

    = 85 × 20/100

    = 17

    So the balance number of mangoes = 85 – 17 = 68

    Therefore, 198 mangoes were in good condition.

  • Question 11
    1 / -0

    6 ¼ % of what number is 375?

    Solution

    Consider x as the number

    6 ¼ % of x = 375

    By further calculation

    25/ (4 × 100) of x = 375

    So we get

    1/16 x = 375

    Here

    x = (375 × 16)/ 1 = 6000

    So the number is 6000.

  • Question 12
    1 / -0

    A shop worth ₹ 100000 was insured for 89% of its value. How much would the owner get in case of any mishappening?

    Solution

    Worth of shop = ₹ 100000

    Amount insured = 89% of its values

    We can write it as

    = 89% of ₹ 100000

    So we get

    = ₹ 100000 × 89/100

    = ₹ 89000

  • Question 13
    1 / -0

    Express:0.0075 as percent

    Solution

    0.0075 as percent

    We can write it as

    0.0075× 100 = 0.75%

  • Question 14
    1 / -0

    Express:1 m 20 cm as percent of 2 m 50 cm

    Solution

    1 m 20 cm as percent of 2 m 50 cm

    We know that 1m = 100 cm

    We can write it as

    1 m 20 cm as percent of (1 × 100 + 20) cm = 120 cm

    2 m 50 cm as percent of (2 x 100 + 50) cm = 250 cm

    So we get

    = (120/250) × 100

    By further calculation

    = 12 × 4

    =48%

  • Question 15
    1 / -0

    A class has 60 boys and 50 girls. What is the percentage of boys in the class?

    Solution

    Number of boys = 60

    Number of girls = 50

    So the total number of children = 60 + 50 = 110

    So the percentage of boys in the class = (60/110) × 100

    We get

    =600/11

    = 54611%
