Thus there were 56 singers.

Step-by-step explanation:

10% is written = 10/100 = 0.1

80% is written as = 100 / 80 = 0.80

As given

7 is 10% of y

Than the equation becomes

7 = 0.10 × y

y = 7 / 0.10

y = 7 x 100 / 10

y = 700 / 10 = 70

As we are given

n is 80% of y

Than the equation becomes

n = 0.80 × y

Put the value of y in the above

n = 0.80 × 70

n = 56

Thus there were 56 singers.
