Question

A tin of biscuits contains shortbread and choc-chip biscuits in the ratio 2:3.
The tin contains 40 biscuits.
How many shortbread biscuits are there in the tin?​

Answer 1

Step-by-step explanation:

let common ratio be x.

then 2x + 3x = 20

5x = 20

x = 8

2x = 16

Answer 2

Total no. of biscuits= 40

ratio=2:3

So, 2+3=5

No. of shortbread= 2/5 of 40

= 16

Therefore there were 16 shortbreads.
