Solution:(i) Ratio of original and reduced weight of woman = 7: 5

Consider original weight = 7x

Reduced weight = 5x

Here original weight = 91 kg

So the reduced weight = (91 × 5x)/ 7x = 65 kg

(ii) Amount collected for charity = Rs 2100

Here the ratio between orphanage and a blind school = 3: 4

Sum of ratios = 3 + 4 = 7

We know that

Orphanage schools share = 2100 × 3/7 = Rs 900

Blind schools share = 2100 × 4/7 = Rs 1200
