Question

Two whole numbers whose sum is 72 cannot
be in the ratio?
(A) 5:7
(B) 3:5
(C) 3:4
(D) 4:5​

Answer 1

Ans = 3:4

because, 5:7 = 5/7

5/7 × 6/6 = 30/42

30 + 42 = 72

3:5 = 3/5

3/5 × 9/9 = 27/45

27 + 45 = 72

4:5 = 4/5

4/5 × 8/8 = 32/40

32 + 40 = 72

but for 3:4 it doesn't happen with any number
