W/M = 3/7
W1/M1 = 1/9 W2/M2 = 2/3
So Q1/Q2 = (2/3 - 3/7)/(3/7 - 1/9)
= (14 - 9)/21/(27 - 7)/63 = 5/21 * 63/20 = 3/4
(1) is sufficient
(2)
For Solution 1
M = W + 80
M + W = 100
For Solution 2
M = W + 10
M + W = 50
So we can find the ratios of M:W in solutions and using above alligation technique find the required ratio.

Hi Karishma,
Why is the ratio of S1 to S2 not equal to 1/2, by using this method:
W1/M1 = 1/9 W2/M2 = 2/3
So Q1/Q2 = (2/3 - 3/7)/(3/7 - 1/9)
= (14 - 9)/21/(27 - 7)/63 = 5/21 * 63/20 = 3/4
Which one is correct?
