Question

out of 150 apples in a basket, 30 apples are found rotten. find: (a) the ratio of rotten apples to the number of good apple's. (b) the ratio of good apples to the total number of apples. (c) the ratio of rotten apples to the total number of apples.

Answer 1

Given total number of apples=150
Number of rotten apples=30
Number of good apples=150-30=120
(a) Required ratio=30÷120=1÷4=1:4(Ans.)
(b)Required ratio=120÷150=4÷5=4:5(Ans.)
(c) Required ratio=30÷150=1÷5=1:5(Ans.)

Answer 2

Total apples = 150

rotten apples = 30

(a) rotten apples = 30

good apples = 150 - 30 = 120

ratio = 30 : 120

ratio in simplest form = 1 : 4

(b) good apples = 120

total apples = 150

ratio = 120 : 150

ratio in simplest form = 4 : 5

(c) rotten apples = 30

total apples = 150

ratio = 30 : 150

ratio in simplest form = 1 : 5
