Question 16 Percentage Exercise 12.2

A motorist travelled 122 kilometers before his first stop. If he had 10%of hisjourney to complete at this point, how long was the total ride?


Given details are,

Motorist total distance travelled before first stop = 122 km

Journey completed at first stop = 10 %

Let us consider total ride to be travelled be ‘x’ km

So, by calculating

(x/100) × 10 = 122

By cross multiplying we get,

x/100 = 122/10

x = (122 × 100)/10

= 1220 km

∴ Motorist total ride is 1220 km
