Answer 1

P = Q + R + S

Q = (P+R+S)/3

R = (P+Q+S)/5

S = (P+Q+R)/11

P + S = 210

Q = (P+R+S)/3

3Q = P + S + R

3Q = 210 + R

R = (P+Q+S)/5

5R = 210 + Q

Q = 5R - 210

3(5R - 210) = 210 + R

15R - 630 = 210 + R

14R = 210 + 630 = 840

R = 840 /14 = 60

Q = 5R - 210 = 5x60 - 210 = 300 - 210 = 90

Sum of the two amounts = 60 + 90 = Rs 150
