- A 270 metres long train running at the speed of 120 kmph crosses another train running in the opposite direction at the speed of 80 kmph in 9 seconds. What is the length of the other train?

(a) 230 m

(b) 240 m

(c) 260 m

(d) 320 m

Ans: (a) 230 m

Explanation:

Relative speed = (120 + 80) km/hr = 200 km/hr

Converting to m/s:

Relative speed = 200×5/18 m/sec = 500/18 m/sec

Time taken = 9 seconds

Let the length of the other train be x meters.

According to the formula:

x+170/9 = 500/18

Solving for

x+270=500

x=230 - The angle of elevation of the sun, when the length of the shadow of a tree is 3 times the height of the tree, is:

(a) Rs. 45

(b) Rs. 50

(c) Rs. 55

(d) Rs. 60

Answer: (d) Rs. 60

Explanation:

The cost price (C.P.) of 17 balls minus the selling price (S.P.) of 17 balls equals the C.P. of 5 balls.

C.P. of 12 balls = S.P. of 17 balls = Rs. 720.

Therefore, the C.P. of 1 ball = Rs. 720 / 12 = Rs. 60. - Aman started a business by investing Rs. 70,000.

= [(900)2 – 807296]

= 810000 – 807296

= 2704. - 4.036 divided by 0.04 gives:

(a) 160

(b) 175

(c) 180

(d) 195

Answer: (b) 175

Explanation: Suppose the man works overtime for x hours.

Now, working hours in 4 weeks = (5 x 8 x 4) = 160.

160 x 2.40 + x x 3.20 = 432

3.20x = 432 – 384 = 48

x = 15.

Hence, total hours of work = (160 + 15) = 175. - If A + B means A is the mother of B; A – B means A is the brother of B; A % B means A is the father of B; and A x B means A is the sister of B, which of the following shows that P is the maternal uncle of Q?
