Question

The bus fare between two cities is increased in the ratio 7: 9. Find the increase in the fare, if:

(i) the original fare is Rs 245;

(ii) the increased fare is Rs 207.

Solution

According to the given information,

Increased (new) bus fare = `9/7` original bus fare

(i) We have:

Increased (new) bus fare = `9/7` x Rs 245 = Rs 315

 Increase in fare = Rs 315 - Rs 245 = Rs 70

(ii) We have:

Rs 207 = `9/7` x original bus fare

Original bus fare = `"Rs"  207 xx 7/9` = Rs 161

 Increase in fare = Rs 207 - Rs 161 = Rs 46

  Is there an error in this question or solution?
