UPSC Prelims 2026 CSAT Paper 2 — Question 38

Question

The ratio of male to female workers in two companies A and B is 13 : 10 and 7 : 5, respectively. If both the companies have the same number of female workers, then what is the ratio of the total number of workers in A to those in B?

(a)24 : 23
(b)23 : 24
(c)18 : 17
(d)27 : 18

UnlockIAS answer: (b)23 : 24

Solution

Take equal female counts = 10. Then A = 13 + 10 = 23; for B, scaling 7 : 5 to 14 : 10 gives total 24. So A : B = 23 : 24.
