Quantitative Aptitude(IBPS CL) Ratio, Proportion

There are 3 clubs A, B and C and the ratio of the total population visit in the club is 10 : 12 : 9 respectively. If the number of males visit in club A is 35%, in club B is 45% and in club C is 40% of total population, then find the ratio of total males and females visit in the all clubs together.

Explanation:

Let’s break it down:

- Clubs A, B, and C have population ratios of 10 : 12 : 9, so total = 10x, 12x, and 9x.

- Males in A: 35% of 10x = 3.5x

- Males in B: 45% of 12x = 5.4x

- Males in C: 40% of 9x = 3.6x

- Add males: 3.5x + 5.4x + 3.6x = 12.5x

- Total population: 10x + 12x + 9x = 31x

- Females = total - males = 31x - 12.5x = 18.5x

So, ratio males:females = 12.5x : 18.5x = 25 : 37

Option 5 is the correct answer.

A quick rundown of the other options:

- 29:33, 25:33, 22:37, 22:35 don’t match up mathematically with the breakdown above. If you work through each, you’ll find the ratios don’t reduce to the math calculated.

This one’s clear: 25 : 37 is the one that fits.
