Question

A loaf of bread is cut into 2 parts in the ratio 3 : 8. If the length of longer part is 16 cm. Find the original length of the bread.​

Answer 1

Step-by-step explanation:

let the original length of bread be x

Total number of parts = 5 + 3 = 8

=> Length of longer part = 5/8 x

Length of shorter part = 3/8 x

According to the question

5/8x - 3/8x = 16

5-3/8x=16

2/8x=16

x=16×8/2

=>x=8×8=64cm

Therefore, actual length of bread is 64 cm.

Thus, longer part of bread :

= 5/8 x

= 5/8 × 64

= 5 × 8

= 40 cm

Therefore, the longer part of the bread is 40 cm.
