Validate

Solution:

Total pocket money of three friends = 3 × 80 = Rs 240
Money spent by A = x
Money spent by B = 2
xMoney spent by C = 3x
Average of unspent money = Rs 60
Total unspent money = Rs 180
Spent money = 240 -180 = Rs 60
Money spent by A, B and C = 60

x+2x+3x=60

6x=60

x = 10

Money spent by A = Rs 10
