Question
It was estimated that because of people switching to Metro trains, about 33000 tonnes of CNG, 3300 tonnes of diesel and 21000 tonnes of petrol was saved by the end of year 2007. Find the fraction of the quantity of diesel saved to the quantity of petrol saved.
Solution
Given, quantity of CNG saved = 33000 tonne
Quantity of diesel saved = 3300 tonne
Quantity of petrol saved = 21000 tonne
Fraction of the quantity of diesel saved to the quantity of petrol saved = `3300/21000`
= `33/210 = (33 ÷ 3)/(210 ÷ 3)` ......[∵ HCF of 33 and 210 is 3]
= `11/70`
