# Find the whole quantity if

(a) 5% of it is 600 (b) 12% of it is ₹1080 (c) 40% of it is 500 km

(d) 70% of it is 14 minutes (e) 8% of it is 40 litres

**Solution:**

(a) 5% of it is 600

Assume the whole quantity to be A.

We know that, 5% = 5/100

Since, 5% of it is 600

So, 5/100 × A = 600

A = 600 × 100/5

= 12000

(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

(d) 70% of it is 14 minutes.

Assume total time to be A.

Since 70% of it is 14 minutes.

So, 70/100 × A = 14

A = 14 × 100/70

= 20 minutes

(e) 8% of it is 40 litres.

Assume the total amount to be A.

Since 8% of A is 40 litres

So, 8/100 × A = 40

A = 40 × 100/8

= 500 litres

**Video Solution:**

## Find the whole quantity if (a) 5% of it is 600. (b) 12% of it is ₹1080. (c) 40% of it is 500 km. (d) 70% of it is 14 minutes. (e) 8% of it is 40 litres.
