12 3/4 * (1 2/17 / 8 1/6) / 5 4/3 = __________?
12 3/4 * (1 2/17 / 8 1/6) / 5 4/3 = __________?A. 1
B. 27/98
C. 6/17
D. 27/17
Explanation:
By applying BODMAS rule.
51/4 * (19/17 / 49/6) / 19/3
= 51/4 * ( 19/17 * 6/49) * 3/19 = 27/98The C.I. on a certain sum for 2 years at 10% per annum is Rs. 525. The S.I. on the same sum for double the time at half the rate percent per annum is________?
The C.I. on a certain sum for 2 years at 10% per annum is Rs. 525. The S.I. on the same sum for double the time at half the rate percent per annum is________?A. Rs. 400
B. Rs. 500
C. Rs. 600
D. Rs. 800
Explanation:
Let the sum be Rs. P. Then,
[P(1 + 10/100)2 – p] = 525
P[(11/10)2 – 1] = 525
P = (525 * 100) / 21 = 2500
Sum = Rs. 2500
So, S.I. = (2500 * 5 * 4)/100 = Rs. 500A invested some money in 10% stock at 96. If B wants to invest in an equally good 12% stock, he must purchase a stock worth of__________?
A invested some money in 10% stock at 96. If B wants to invest in an equally good 12% stock, he must purchase a stock worth of__________?A. Rs. 80
B. Rs. 115.20
C. Rs. 120
D. Rs. 125.40
For an income of Rs. 10, investment = Rs. 96.
For an income of Rs. 12, investment = Rs ( 96/10 X 12 )
= Rs. 115.20The ratio of the length and the breadth of a rectangle is 4 : 3 and the area of the rectangle is 6912 sq cm. Find the ratio of the breadth and the area of the rectangle?
The ratio of the length and the breadth of a rectangle is 4 : 3 and the area of the rectangle is 6912 sq cm. Find the ratio of the breadth and the area of the rectangle?A. 1 : 96
B. 1 : 48
C. 1 : 84
D. 1 : 68
Let the length and the breadth of the rectangle be 4x cm and 3x respectively.
(4x)(3x) = 6912
12×2 = 6912
x2 = 576 = 4 * 144 = 22 * 122 (x > 0)
=> x = 2 * 12 = 24
Ratio of the breadth and the areas = 3x : 12×2 = 1 : 4x = 1: 96.Two numbers are respectively 20% and 25% more than a third number. The percentage that is first of the second is_________?

What percent of 125 is 16?A. 10 2/5%
B. 12 3/5%
C. 11 1/5%
D. None of these
Explanation:
Let the required percentage be x%.
x% of 125 = 16 => x/100 * 125 = 16
=> x = 1600/125 = 64/5 = 12 4/5
