d) 1000
Ans: 1111
12. Six friends decide to share a big cake. Since all of them like the cake, they begin quarreling who gets to first cut and have a piece of the cake. One friend suggests that they have a blindfold friend choose from well shuffled set of cards numbered one to six. You check and find that this method works as it should simulating a fair throw of a die. You check by performing multiple simultaneous trials of picking the cards blindfold and throwing a die. You note that the number shown by the method of picking up a card and throwing a real world die, sums to a number between 2 and 12. Which total would be likely to appear more often 8,9 or 10?
a) 8
b) 9
c) 10
d) None
Ans: 8
Soln: the combinations for 8 r (4,4) (5,3) (3,5) (6,2) (2,6)

13. For the FIFA world cup, Paul the octopus has been predicting the winner of each match with amazing success. It is rumored that in a match between 2 teams A and B, Paul picks A with the same probability as A,s chances of winning. Let,s assume such rumors to be true and that in a match between Ghana and Bolivia, Ghana the stronger team has a probability of 5/6 of winning the game. What is the probability that Paul will correctly pick the winner of the Ghana-Bolivia game?
a) 0.72
b) 0.81
c) 0.77
d) 0.75
Ans: 0.72
Soln: probability of one is 5/6
So probability of other = 1/6
Probability of choosing winner =1/6*1/6 + 5/6 *5/6 = 26/36 = 0.72
14. A grandmother has daughter n granddaughter. Grandmothers age in years is same as grand daughters age in months. And granddaughters age in days is same as daughters age in week den some irrleeeeeeevant data.. d final problem was to find grandmothers age?

16. Loooots of unnecessary stuuuuuuuffff. A man walks on a hill at a speed of 6 kmph and walked back d same hill wid steep slope at d speed of 8 kmph. Wat is his average speed of d journey?
a) 6.86
b) 6
c) 7.76
d) 6.23
Ans: 6.86
Soln: avg speed=2xy/(x+y)
17. If log(m,n)=m^n. den log(10,m)=nlog(2,2). Den find d value of n.
a) 25
b) 10
c) 20
d) 4
Ans: 25
Soln: 10^m=n*2^2=4n
10^m=4n
So here if v take n=25 v get 100 which is compatible wid LHS(i.e smethin of the form 10^smethin)
18. A long story, den. Ajay is taller den suresh, joe is nt taller den ajay. Den wat is true?
Ans: cannot b determined
19. A company manufactures robots. The material cost, labour cost and overhead cost ar in ratio 4:5:3. If material cost is 108. Find the total cost of robot?
a) 324
b) 342
c) 366
d) 314
Soln: [4/(4+5+3)]*total cost = 108
So total cost=324
20. The length of a rectangle is increased by 40% n breadth is decreased by 20%. What is the increment/decrement in new area?
a) 12% decrement
b) 12% increment
c) 10% decrement
d) 10% increment
Ans: 12% increment
Soln: L2=L1 + 40/100 L1=140/100 L1
B2=B-20/100 B1=80/100 B1
New area=L2*B2
Old area=L1*B1
Taking d ratio of dis two v get new area=112% old area
So area increased by 12%
