Question

Find the number : 40% of a number is IO?​

Answer 1

Answer:

the number is 25

Step-by-step explanation:

40% of a number is 10

Let the numbe be "a"

40% of "a" is 10.

$\frac{40}{100} \times a = 10$

$\frac{4a}{10} = 10$

$4a = 10 \times 10 \\ 4a = 100 \\ a = \frac{100}{4}$

$a = 25$

the number is 25.

Answer 2

Given

40% of a =10

40/100×a =10

4/10×a =10

4a = 10×10

4a =100

a=100/4

a= 25

Therefore required number is 25
