= [450 × (30/100) × (7/15)] + [400 × (18/100) × (5/12)] / [450 × (30/100) × (8/15)] + [400 × (18/100) × (7/12)]
= (63+30)/(72+42) = 93/114 = 31/38 = 31 : 38Incorrect
Answer – 2) 31:38
Explanation:
Required ratio = French (L + O) males / French (L + O) females
= [450 × (30/100) × (7/15)] + [400 × (18/100) × (5/12)] / [450 × (30/100) × (8/15)] + [400 × (18/100) × (7/12)]
