Question

find the whole quantity if. 1) 10% of it is 800. 2) 50% of it is 500 km. 3) 8% of it is 40 litres​

Answer 1

Step-by-step explanation:

(1)

10% of x = 800

=> (10/100) * x = 800

=> 10x = 80000

=> x = 8000

(ii)

50% of it is 500 km

=> (50/100) * x = 500

=> x/2 = 500

=> x = 1000

(iii)

8% of it is 40 litres

=> (8/100) * x = 40

=> 8x = 4000

=> x = 500

Hope it helps!
