increased by
a) 40%
b) 42% c) 44% d) 20%​

Answer 1

Answer:

44%

Step-by-step explanation:

Let the number be x

We are given that A number is increased consecutively two times by 20% each

Number after first increase = x+20\% \times xx+20%×x

= 1.2x1.2x

Number after second increase = 1.2x+20\% \times 1.2x1.2x+20%×1.2x

= 1.44x1.44x

Difference in original and final number = 1.44x-x=0.44x1.44x−x=0.44x

So, the original number is actually increased by \frac{0.44x}{x} \times 100=44\%
