​

Answer 1

Answer:

(a) 5% of it is 600.

Answer: Let us assume the whole quantity =x=x

x×5100=600x×5100=600

Or, x=600×1005=12000x=600×1005=12000

(b) 12% of it is Rs. 1080.

Answer: Let us assume the whole quantity =x=x

x×12100=1080x×12100=1080

Or, x=1080×10012=9000x=1080×10012=9000

(c) 40% of it is 500 km.

Answer: Let us assume the whole quantity =x=x

x×40100=500x×40100=500

Or, x=500×10040=1250x=500×10040=1250 km

(d) 70% of it is 14 minutes.

Answer: Let us assume the whole quantity =x=x

x×70100=14x×70100=14

Or, x=14×10070=20x=14×10070=20 min

(e) 8% of it is 40 litres.

Answer: Let us assume the whole quantity =x=x

x×8100=40x×8100=40

Or, x=40×1008=500x=40×1008=500 liter
