Answer 2

let the 10 rupees card be a

Then, 5 rupees card be 2xa/3=2a/3

and 15 rupees card be 2xa/3=2a/3

A/q

Rs.245=(Rs.10xa) +(Rs.5x2a/3)+(Rs.15x2a/3)

Rs.245=(Rs.10a)+(Rs.10a/3)+(Rs.10a)

Rs.245=Rs.20a+Rs.10a/3

Rs.245=Rs.60a+Rs.10a/3

Rs.245=Rs.70a/3

a=Rs.245xRs.3/70

a=Rs.735/70

a=Rs.10.5

HENCE,

Rs.10=a=Rs.10.5

Rs.5=Rs.2a/3=Rs.2x10.5/3=Rs.7

Rs.15=Rs.2a/3=Rs.2x10.5/3=Rs.7
