Question

$100 \times 20 = 70 \times x + 30 \times 0 |?|$
​

Answer 1

Answer:

As, in the statement

100 × 20 = 70 × x + 30 × 0

We have to find the value of x.

So,

100 × 20 = 70 × x + 30 × 0

2000 = 70x + 0

2000/70 = x

200/7 = x

28.57(approx) = x ..........[Answer]

Hence, the value of x is 28.57(approx)

Answer 2

100 × 20 = 70× x + 30

⇒ 2000-30=70x

⇒ 70x = 1700

⇒ x = 1700/70

⇒ x = 170/7

⇒ x = 24.2857142857

⇒ x = 24. 3 approx.
