by
A. 120
B. 80
C. 192
D. 48
✅ The correct answer is option D. 48.
If A invests amount C1 for T1 time and his share of profit is P1, and B invests amount C2 for T2 time and his share of profit is P2, then, C1 * T1 / C2 * T2 = P1/P2

If P is the Nasir’s share of profit, then Changaz gets (240 – P)

Therefore, 6000 * 12 / 3000 * 6 = (240 – P) / P = 72/ 18 = 4

4P = (240 – P)

5P = 240

P = 48

373. At 10 a.m. two trains started traveling toward each other from stations 287 miles apart. They passed each other at 1:30 p.m. the same day. If the average speed of the faster train exceeded the average speed of the slower train by 6 miles per hour, which of the following represents the speed of the faster train, in miles per hour?

by
A. 38
B. 40
C. 44
D. 48
✅ The correct answer is option C. 44.
Let the speed of the faster train be x miles per hour and

the distance travelled by it when it meets the slower train be y miles. Time taken by the faster train to cover y miles

= Time taken by the slower train to cover (287-y) miles

= 3.5 hours (y/x) = (287-y)/(x-6) = 3.5 Solving, x = 44 miles/hr
