Question 2
1 / -0

Harsh bought some groceries for his home. He spent Rs. 14.00 on biscuits. One bottle of juice cost Rs. 20. He bought 4 bottles and then he bought corn flakes. He spent Rs. 100 altogether. Find the cost of corn flakes.

A
Rs. 2

B
Rs. 6

C
Rs. 12

D
Rs. 17

Solution

1 bottle of juice = Rs. 20
4 bottles of juice = Rs. 20 × 4 = Rs. 80

Biscuits = Rs. 14
Total money spent = Rs. 100

=> 80 + 14 + Corn flakes = Rs. 100
=> Cost of corn flakes = Rs. 100 - Rs. 94 = Rs. 6

So, the cost of corn flakes = Rs. 6
Question 3
1 / -0

What will we get when we add 269.15 to 96.10 and subtract it from the product of 12 x 34?

A
42.75

B
62.65

C
70.20

D
71.36

Solution

Sum of the given numbers, 269.15 + 96.10 = 365.25
Product = 12 x 34 = 408
Thus, according to question,
408 - 365.25 = 42.75

1 / -0

Which of the following numbers is the smallest?

A
0.190

B
0.099

C

Solution

0.190 - 1 tenths and 9 hundredths

0.099 - 0 tenths, 9 hundredths and 9 thousandths

0.990 - 9 tenths and 9 hundredths

0.910 - 9 tenths, 1 hundredths

Therefore, 0.099 is the smallest among the four given numbers.
