The average pocket money of 3 friends A, B, C is Rs.80 in a particular month. If B spends double and C spends triple of what A spends during that month and if the average of their unspent pocket money is Rs.60, then A spends (in Rs.)
Explanation:
According to the question Pocket money = A + B + C /3 = 80
= A + B + C = 240
Unspent pocket money = A+B+C/3 = 60
= A + B + C = 180
Spent Pocket money = 240 - 180 = Rs 60.
A spend = 1 x 10 = 10 rs
Hence, option 1 is the correct answer.
