Question

if a number is increased by 20% and the resulting number is again increased by 20% , what per cent is the total increase.​

Answer 1

Answer:

44%

Step-by-step explanation:

Lets assume the number as Y

Y x (20/100) = Y₁

Y₁ x (20/100) = Y₂ = [Y + (Y x 44/100)]

Lets check with an example... Let the number Y be 100,

20% of 100 = 20 => Y₁ = 120

Y₁ x (20/100) => 20% of 120 = 24 => Y₂ = 144

As given, Y + (Y x 44/100), I.E 100 + (44% of 100)

100 + 100 x 0.44 = 100 + 44 = 144...

Therefore total increase is 44%...

I hope u understand....
