Ravi purchased a bike for Rs.60000/-. He sold it at a loss of 8 percent. With that money he again purchased another bike and sold it at a profit of 10 percent. What is his overall loss/profit?

Correct

Explanation:
CP = Rs.60000
SP = 92/100 * 60000 = 55200
SP of another bike = 110/100 * 55200 = 60720
Overall Profit = 60720 – 60000 = 720

Incorrect

Explanation:
CP = Rs.60000
SP = 92/100 * 60000 = 55200
SP of another bike = 110/100 * 55200 = 60720
Overall Profit = 60720 – 60000 = 720

Rakesh has two bags, “A” and “B” that contain green and blue balls. In the Bag ‘A’ there are 6 green and 8 blue balls and in the Bag ‘B’ there are 6 green and 6 blue balls. One ball is drawn out from any of these two bags. What is the probability that the ball drawn is blue?

Correct

Explanation :
Total balls in A bag = 14, Total balls in A bag = 12
A bag = 1/2(8c1/14c1) = 2/7
B bag = 1/2(6c1/12c1) = 1/4 —> total Probability = 2/7 + 1/4 =15/28

Incorrect

Explanation :
Total balls in A bag = 14, Total balls in A bag = 12
A bag = 1/2(8c1/14c1) = 2/7
B bag = 1/2(6c1/12c1) = 1/4 —> total Probability = 2/7 + 1/4 =15/28

I. The area of the rectangle is 252 sq m.
II. The ratio of length to breadth of the rectangle is 7:4 respectively.

Correct

Explanation :
From Statement I,
A = 252 sq.m
From Statement II,
7x * 4x = 252; x =3
Perimeter = 2(21 + 12) = 66m

Incorrect

Explanation :
From Statement I,
A = 252 sq.m
From Statement II,
7x * 4x = 252; x =3
Perimeter = 2(21 + 12) = 66m

What is the rate of interest p.c.p.a?
I. An amount of Rs.14,350 gives a simple interest of Rs 11,480 in four years .
II. The amount doubles itself in 5 years with simple interest .

Correct

Explanation :
From Statement I,
R = SI * 100 / P * T = 11480 * 100 / 14350 * 4 = 20%
From Statement II,
P = x, A = 2x, A – P = SI = x T = 5 yrs
R = SI * 100 / P * T = x * 100 / x * 5 = 20%

Incorrect

Explanation :
From Statement I,
R = SI * 100 / P * T = 11480 * 100 / 14350 * 4 = 20%
From Statement II,
P = x, A = 2x, A – P = SI = x T = 5 yrs
R = SI * 100 / P * T = x * 100 / x * 5 = 20%
