  • Question 1
    1 / -0

    Two cyclists met each other at 10 a.m. on Ferozepur road. After their meeting, one of them proceeded in the north direction and the other proceeded in the east direction. Exactly at noon, they were 60 km apart. If the difference between their speeds was 6 km/hr, then find the speed of the faster cyclist.

    Solution

    Let the speed of the slower cylclist be x km/hr.
    So, the speed of the faster one will be (x + 6) km/hr.
    The distance travelled in 2 hr is 2x and 2(x + 6) km.

    From Pythagoras theorem:
    (2x)+ [2(x + 6)]2 = (60)2
    4x2 + 4(x2 + 36 + 12x) = 3600
    8x2 + 48x + 144 = 3600
    x2 + 6x - 432 = 0
    (x - 18)(x + 24) = 0
    x = 18 or -24 (neglected)
    So, the speed of the faster cyclist is 24 km/hr.

     

  • Question 2
    1 / -0

    If three pieces of timber 42 m, 49 m and 63 m long have to be divided into planks of the same length, what is the maximum possible length of each plank?

    Solution

    Maximum possible length would be the HCF of the three given measurements.
    42 = 2 × 3 × 7
    49 = 7 × 7
    63 = 3 × 3 × 7
    Therefore, the longest possible length of each plank is 7 m.

     

  • Question 3
    1 / -0

    Three different containers contain different quantities of mixture of milk and water, whose measurements are 403 kg, 434 kg and 465 kg. What biggest measure must be used to measure all the different quantities exactly?

    Solution

    HCF of all the measurements:
    403 = 13 × 31
    434 = 2 × 7 × 31
    465 = 3 × 5 × 31
    Therefore, the largest measure is 31 kg.

     

  • Question 4
    1 / -0

    Raghav sold two books having the same cost price, one for Rs. 673 and the other for Rs. 467. The profit he attained on selling the book for Rs. 673 was equal to the loss he incurred on selling the other book for Rs. 467. Find out the cost price of one book.

    Solution

    Let CP of each book be X.
    From the above given values,
    Profit by selling book for Rs. 673 = Loss by selling book for Rs. 467
    673 - X = X - 467
    2X = 673 + 467
    2X = 1140
    X = Rs. 570
    Therefore, cost price of one book = Rs. 570

     

  • Question 5
    1 / -0

    After purchasing a few stationery items at cost price of Rs. 800, Aman sold half of the items at a profit of 10%. Calculate the profit percentage at which he must sell the remaining items in order to attain the overall gain of 22%.

    Solution

    Let the items purchased by Aman = 100i at cost of 100c for each item.
    Therefore,
    100i × 100c = Rs. 800
    Now, consider profit percentage of remaining goods = p
    Then,
    50i × 110c + (50i) × (100c + p) = (100i) × (122c)
    ⇒ 50p = 1700c
    ⇒ p = 34c
    So, the profit percent at which Aman must sell the remaining items to have overall profit of 22% is 34%.

     

  • Question 6
    1 / -0

    A group of three friends named Ria, Reena and Richa initiated a gift packing business by infusing Rs. 26,000, Rs. 39,000 and Rs. 52,000, respectively. Richa quit the partnership after 8 months. The business attained a profit of Rs. 46,000 after completion of one year. Calculate the amount that Richa holds in the profits.

    Solution

    From the given values, the respective shares in terms of ratio for Ria, Reena and Richa in the attained profits
    = 26,000 × 12 : 39,000 × 12 : 52,000 × 8 = 6 : 9 : 8

    Share of profit attained by Richa after 8 months = [8/(6 + 9 + 8)] × 46,000 = Rs. 16,000

     

  • Question 7
    1 / -0

    Radha gained 25% on selling a doll to Seema. Seema further sold the doll to Karishma with 15% profit. The profit made by Seema was Rs. 25 less than that made by Radha. Determine the cost of the doll purchased by Radha.

    Solution

    Assume the cost price of doll to be Rs. c.
    Now, profit made by Radha = 25/100 × c = 0.25c
    Price at which Radha sold the doll = c + 0.25c = 1.25c
    Cost price of the doll for Seema = 1.25c
    Profit made by Seema = 15/100 × 1.25c = 0.1875c
    As per the given question,
    0.25c = 0.1875c + 25
    0.0625c = Rs. 25
    c = Rs. 400
    Required cost = Rs. 400
