Question

What is 20% of number whose 35% is 70.​

Answer 1

let the number be x

35% of x = 70

$\frac{ \cancel{35}}{100} \times x = \cancel{ 70}$

$\frac{ 1}{ {100}} \times x = 2$

$x = 200$

Now...

20% of 200

$\frac{20}{ \cancel{100}} \times \cancel{200}$

$= 20 \times 2$

$\bf= 40$

Answer 2

let the number be x

35% of x = 70

$\frac{ \cancel{35}}{100} \times x = \cancel{ 70}$

$\frac{ 1}{ {100}} \times x = 2$

$x = 200$

Now...

20% of 200

$\frac{20}{ \cancel{100}} \times \cancel{200}$

$= 20 \times 2$

$\bf= 40$
