​

Answer 1

Step-by-step explanation:

Given that:-

Let the number be X

40% of the number=40% of X

=>(40/100)×X

=>(2/5)X

=>2X/5

If the number is increased by 40% then it becomes 42

=>X+(2X/5)=42

=>(5X+2X)/5=42

=>7X/5=42

=>7X=42×5

=>7X=210

=>X=210/7

=>X=30

The number =30

check:-

30+(40%of 30)

=>30+(40×30/100)

=>30+(4×3)

=>30+12

=>42
