A train M leaves Meerut at 5 a.m. and reaches Delhi at 9a.m. Another train N leaves Delhi at 7 a.m. and reaches Meerut at 10.30 a.m. At what time do the two trains cross one another?

(a) 8.26 a.m.

(b) 8.00 a.m.

(c) 7.36 a.m.

(d) 7.56 a.m.

**Answer: (d) 7.56 a.m. **

**Solution:-**

According to the question,

Then

(X/3.5) x t + (X/4) x (t+2)= X

or

t/3.5 + (t+2)/4 =1

Then

t= 7/7.5 hrs or 56 mins.

So trains will meet at 7.56 a. m.

Hence, the correct answer is option (d) 7.56 a. m.
