(Set – 40)
1) Ravi and Kishan start from the same point but, in opposite direction towards each other and run around a rectangular park of area 1950 m2. It is known that the length of the park is 53 m more than the breadth of the park. Ravi runs at ‘2x’ m/s and Kishan runs at ‘3x’ m/s and they meet for the first time in (103/15) seconds. How long would it have take them to meet each other if both of them ran at ‘x’ m/s towards each other?
a) 1126/11 seconds
b) 92/7 seconds
c) 103/6 seconds
d) 215/13 seconds
e) None of these
2) What is selling price of table fan it Dealer sells at a profit of 15%?
l. Dealer marks fan 60% above cost price and allows a discount of 25%. It no discount is offered then he would get 120 more profit.
ll. Dealer marks fan 75% above cost price and after allowing two successive discounts of 20% sold to Vijay, Vijay sold it to Viru for 720 and claims a profit of 25%.
Ill. Dealer marked fan 75% above cost price and after allowing a discount of 25% sells to customer. If he allows an addition discount of 20% he would get 260 less.
3) What is length of train P?
l. Train P crosses a platform of length 350 meter and train Q running in opposite direction having length 220 meter in 14.5 sec and 8.3 sec respectively.
ll. Train Q crosses a platform of length 365 meter in 29.75 sec and train P running at in same direc-tion in 50.5 sec, considering speed of train P is more than train Q.
Ill. Train Q crosses a platform and a car running at a speed of 25 m/sec in opposite direction in 26 sec and 8 sec respectively.

4) A man draws 3 balls from the bag A one after the other without re-placement. Find the probability that all the three balls drawn are not black in color?
a) 1/250
b) 229/250
c) 339/340
d) 349/350
e) None of these
5) If one ball from each bag is drawn at random, then what is the proba-bility of the event, that one red ball is from bag B and one Brown ball is from bag A?
a) 24/125
b) 8/125
c) 13/25
d) 12/25
e) None of these
7) What is the ratio of probability of drawing two black colour balls from bag A at random to the probability of drawing pink colour balls from bag B at random?
a) 14: 33
b) 104: 35
c) 14: 135
d) 104: 135
e) None of these
