Question

c) In 2009, the rise in the number of Metro train travelers reduced the consumption of
CNG, diesel and petrol. It is estimated that 33000 tonnes of CNG, 3300 tonnes of
diesel, and 21000 tonnes of petrol had been saved in 2009. Find the ratio of
(i).
the quantity of diesel saved to the quantity of petrol saved.
(ii) the quantity of diesel saved to the quantity of CNG saved.​

Answer 1

Answer:

i) 11 : 70

ii) 1 : 10

Step-by-step explanation:

(i) The quantity of diesel saved = 3,300 tonnes

The quantity of petrol saved = 21,000 tonnes

Ratio = 3300

21000

= 33

210

= 33 ÷ 3

210 ÷ 3

= 11

70

The ratio of quantity of diesel saved to the quantity of petrol saved = 11 : 70

(ii) The quantity of diesel saved = 3,300 tonnes

The quantity of CNG saved = 33000 tonnes

Ratio = 3300

33000

= 33

330

= 33 ÷ 33

330 ÷ 33

= 1

10

The ratio of quantity of diesel saved to the quantity of CNG saved = 1 : 10
