5. In a school , the ratio of number of boys is 9 :7 . find the number of boys if the total number of students is 3200 .

1. Cost of a dozen bananas = Rs 36

Cost of 1 banana =

Cost of 7 oranges = Rs 28

Cost of 1 orange =

Required ratio =

2. Terms of 8: 9 are 8 and 9

Sum of terms = 8+9 = 17

Sachin will get of total toffees and Deepa will get

No. of toffees will Sachin get =

and No. of toffees will Deepa get =

3. Terms of 2: 3:5 are 2,3 and 5

Sum of terms = 2+3+5 = 10

A will get of total Rs.

B will get and

C will get

No. of Rs. will A get =

No. of Rs. will B get =

No. of Rs. will C get =

4. Terms of 2: 3 are 2 and 3

Sum of terms = 2+3 = 5

Amit will get and Sumit will get

Sum of money will Amit get =

and Sum of money will Sumit get =
