Question

A box contains x 50 paise coins, 2x one-rupee coins and 5r two-rupee coins. If the total value of
these coins is 50 what is the value of x?​

Answer 1

Answer:

4

Step-by-step explanation:

no of 50p coins=x                 [50p=0.5rp]

no of no of 1rp coins= 2x

no of 2rp coins = 5x

total amount =0.5 * x  +  1 * 2x   +   2*5x = 50

                       0.5x  +  2x  +  10x  =  50

                                 12.5x  =  50

                             x  =  50/12.5  =  4

                                    x=4
