- An order was placed for the supply of a carper whose length and breadth were in the ratio of 3 : 2. Subsequently, the dimensions of the carpet were altered such that its length and breadth were in the ratio 7 : 3 but were was no change in its parameter. Find the ratio of the areas of the carpets in both the cases.
(a) 4 : 3
(b) 8 : 7
(c) 4 : 1
(d) 6 : 5
Ans: (b) 8 : 7
Sol: Let the length and breadth of the carpet in the first case be 3x units and 2x units respectively.
Let the dimensions of the carpet in the second case be 7y, 3y units respectively.
From the data,.
2(3x + 2x) = 2(7y + 3y)
=> 5x = 10y
=> x = 2y
Required ratio of the areas of the carpet in both the cases
= 3x * 2x : 7y : 3y
= 6×2 : 21y2
= 6 * (2y)2 : 21y2
= 6 * 4y2 : 21y2
= 8 : 7 - The sector of a circle has radius of 21 cm and central angle 135o. Find its perimeter?
(a) 91.5 cm
(b) 93.5 cm
(c) 94.5 cm
(d) 92.5 cm
Ans: 91.5 cm
Sol: Perimeter of the sector = length of the arc + 2(radius)
= (135/360 * 2 * 22/7 * 21) + 2(21)
= 49.5 + 42 = 91.5 cm - The length of a rectangle is two – fifths of the radius of a circle. The radius of the circle is equal to the side of the square, whose area is 1225 sq.units. What is the area (in sq.units) of the rectangle if the rectangle if the breadth is 10 units?
(a) 140
(b) 156
(c) 175
(d) 214
Ans: 140 sq.units
Given that the area of the square = 1225 sq.units
=> Side of square = √1225 = 35 units
The radius of the circle = side of the square = 35 units Length of the rectangle = 2/5 * 35 = 14 units
Given that breadth = 10 units
Area of the rectangle = lb = 14 * 10 = 140 sq.units - Mr. Tassawar Javed invested an amount of Rs. 13,900 divided in two different schemes A and B at the simple interest rate of 14% p.a. and 11% p.a. respectively. If the total amount of simple interest earned in 2 years be Rs. 3508, what was the amount invested in Scheme B?
(a) Rs. 6400
(b) Rs. 6500
(c) Rs. 7200
(d) Rs. 7500
Ans: (a) Rs. 6400
Let the sum invested in Scheme A be Rs. x and that in Scheme B be Rs. (13900 – x).
then , (x*14*2/100)+(13900-x)*11*2/100) =3508
28x – 22x = 350800 – (13900 x 22)
6x = 45000
x = 7500.
So, sum invested in Scheme B = Rs. (13900 – 7500) = Rs. 6400. - A man took a loan from a bank at the rate of 12% p.a. simple interest. After 3 years he had to pay Rs. 5400 interest only for the period. The principal amount borrowed by him was :
(a) Rs. 2000
(b) Rs. 10,000
(c) Rs. 15,000
(d) Rs. 20,000
Ans: (c) Rs. 15,000
principal = Rs. ( 100 X 5400/12 X 3 ) = Rs. 15000 - A sum of Rs. 12,500 amounts to Rs. 15,500 in 4 years at the rate of simple interest What is the rate of interest ?
(a) 3%
(b) 4%
(c) 5%
(d) 6%
Ans: (d) 6%
S.I. = Rs. (15500 – 12500) = Rs. 3000.
Rate = ( 100 X 3000/12500 X 4 )% = 6%. - What will be the ratio of simple interest earned by certain amount at the same rate of interest for 6 years and that for 9 years ?
(a) 1 : 3
(b) 1 : 4
(c) 2 : 3
(d) Data inadequate
Ans: (c) 2 : 3
Let the principal be P and rate of interest be R%. So Required ratio = [(P x R x 6/100) / (13 x R x 9/100)] = 6PR/9PR = 6/9 = 2 : 3 - An automobile financier claims to be lending money at simple interest, but he includes the interest every six months for calculating the principal. If he is charging an interest of 10%, the effective rate of interest becomes :_________?
(a) 10%
(b) 10.25%
(c) 10.50%
(d) None of these
Ans: (b) 10.25%
Let the sum be Rs. 100. Then, S.I. for first 6 months = Rs. ( 100 X 10 X 1/100 X 2 ) = Rs. 5. S.I. for last 6 months = Rs. ( 105 X 10 X 1/100 X 2 ) = Rs. 5.25. So, amount at the end of 1 year=Rs.(100 + 5 + 5.25) = Rs. 110.25 Effective rate = (110.25 – 100) = 10.25%. - 26.98% of 6002 + 45.01% of 4199 = ________?
(a) 2500
(b) 3500
(c) 3600
(d) 4500
Ans: (b) 3500
Sol:
27% of 6000 + 45% of 4200 = ?
=> ? = 27/100 * 6000 + 45/100 * 4200
=> ? = 1620 + 1890 = 3510 = 3500 - 24 – [2.4 – {0.24 * 2 – (0.024 – ?)}] = 22.0584
(a) 0.0024
(b) 0.024
(c) 0.24
(d) 0.00024
Ans: (a) 0.0024
Sol:
24 – [2.4 – {0.24 * 2 – (0.024 – ?)}] = 22.0584
24 – [2.4 – {0.48 – (0.024 – ?)}] = 22.0584
24 – [2.4 – 0.48 + 0.024 – ?] = 22.0584
24 – 2.4 + 0.48 – 0.024 + ? = 22.0584
? = 22.0584 – 24.48 + 2.424
? = 24.2824 – 24.48 => ? = 0.0024 - Look at this series: 53, 53, 40, 40, 27, 27, … What number should come next?
