(b) 40% of it is 500 km
plz give full explanaton with steps

Answer 1

Answer:

a and b solution

Step-by-step explanation:

(b) 12% of it is ₹1080.

Assume the total amount to be A.

Since 12% of A is ₹1080.

So,12/100 × A = 1080

A = 1080 × 100/12

= ₹ 9000

(c) 40% of it is 500 km.

Assume total distance to be A.

Since 40% of A is 500 km.

So, 40/100 × A = 500

A = 500 × 100/40

= 1250 km

Answer 2

Answer:

a) 12% of it is ₹1080

sol.

Let the whole quantity be X

Therefore, 12% × X = 1080

or, 12/100 × X = 1080

or, X = (1080 × 100) / 12

or, X = 108000/12

or, X = 9000

Answer:- 12℅ of ₹9000 is ₹1080.

b) 40℅ of it is 500 km

sol.

Let the whole quantity be Y

Therefore, 40℅ × Y = 500

or, 40/100 × Y = 500

or, Y = (500 × 100) / 40

or, Y = 50000/40

or, Y = 1250

Answer:- 40℅ of 1250 km is 500km
