A man buys Rs. 20 shares paying 9 % dividend. The man wants to have an interest of 12% on his money.The market value of each share is : | [
"Rs. 12",
"Rs. 21",
"Rs. 15",
"Rs. 18"
] | C | Solution
Dividend on Rs. 20 = Rs.(9/100x20) = Rs.9/5
Rs. 12 is an income on Rs. 100.
∴ Rs.9/5 is an income on Rs. (100/12 X9/5)= Rs.15

A train 100 m long is running at a speed of 68 kmph. How long does it take to pass a man who is running at 8 kmph in the same direction as the train? | [
"6 sec",
"15 sec",
"12 sec",
"9 sec"
] | A | Speed of the train relative to man = (68 - 8) kmph
= (60* 5/18) m/sec = (50/3)m/sec
Time taken by the train to cross the man
= Time taken by It to cover 100 m at 50/3 m / sec
= 100 *3/ 50 sec = 6sec

A train passes a station platform in 30 seconds and a man standing on the platform in 20 seconds. If the speed of the train is 54 km/hr, what is the length of the platform? | [
"240 m",
"150 m",
"280 m",
"260 m"

Length of the train = (15 x 20)m = 300 m.
Let the length of the platform be x metres.
Then, (x + 300)/30 = 15
--> x + 300 = 450
x = 150m.
