Solve it anyone?​

Answer 1

Answer:

11

Step-by-step explanation:

if there are x coins of 10 rupees , then there will be (× +1) coins of 5 rupees as given in the question.

now

( x + 1 )5 + 10x = 80

5x + 5 +10x = 80

15x = 80 - 5

15x = 75

x = 75/15

x = 5

so number of 10 rupee coin = 5

and 5 rupee coin = 5+1 = 6

total coin = 5+6=11
