Correct Answer - Option 1 : 1 : 1

Given:

Work done by 3 boys + 2 girls = work done by 2 boys + 3 girls

Calculation:

Work done by (3B + 2G) = Work done by (2B + 3G)

⇒ 3B – 2G = 3B – 2G

⇒ 1B = 1G

⇒ B : G = 1 : 1

∴ the ratio of efficiency of boy and girl is 1 : 1.

⇒ Here total 5 member's (3 boys & 2 Girls) work is completed by 5 members (2 boys & 3 girls). In such a case, efficiency will always be 1 : 1.
