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
