Dear Dharma,


Thanks for your prompt response. I could not understand why the equation is x+7 + 7 = 20?

After they met at P,
x+7+7 is distance travelled by Raju
x + 10 + 10 is distance travelled by Ali
When they meet again at Q (7 km from Town B)?

Not sure how this works. Please explain.

Dear Maths guru,


Please help to solve this question.
Raju and Ali started drving towards each other at the same time from Towns A and B respectively. They first met each other 10 km away from Town A. When Raju and Ali reached Towns B and A respectively, they turned back immediately and drove towards each other. If Raju and Ali met again 7 km away from Town B, what is the distance between Town A and B?
