The perimeter of a rectangle is 64 m and the difference between the length and the breadth of the rectangle is 14 m then find the area of the rectangle?
Correct
Answer d
The perimeter of a rectangle = 64 m
2(l + b) = 64
l + b = 32–> (1)
l – b = 14–> (2)
By solving the equations (1) and (2),
2l = 46
l = 23 m
b = 9 m
The area of rectangle = lb = 23*9 = 207 m^{2}
Incorrect
Answer d
The perimeter of a rectangle = 64 m
2(l + b) = 64
l + b = 32–> (1)
l – b = 14–> (2)
By solving the equations (1) and (2),
2l = 46
l = 23 m
b = 9 m
The area of rectangle = lb = 23*9 = 207 m^{2}
Question 12 of 20
12. Question
The average cost of three mobiles A, B and C of a certain company is Rs. 48000. The average cost decrease by 10 % when mobile D of the same company is included, find the cost price of mobile D?
Correct
Answer b
The average cost of three mobiles A, B and C = 48000
Total cost of three mobiles A, B and C = 48000*3 = 144000
Average cost of mobiles A, B, C and D = 48000*(90/100) = 43200
Total cost of Four mobiles A, B, C and D = 43200*4 = 172800
The cost price of mobile D = 172800 – 144000 = Rs. 28800
Incorrect
Answer b
The average cost of three mobiles A, B and C = 48000
Total cost of three mobiles A, B and C = 48000*3 = 144000
Average cost of mobiles A, B, C and D = 48000*(90/100) = 43200
Total cost of Four mobiles A, B, C and D = 43200*4 = 172800
The cost price of mobile D = 172800 – 144000 = Rs. 28800

A can do a piece of work in 25 days, B can do it in 20 days. They started the work together but A left 5 days before the completion of the work. The work has finished in?
Correct
Answer a
(x – 5)/25 + x/20 = 1
(4x – 20 + 5x)/100 = 1
9x – 20 = 100
9x = 120
X = 120/9 = 13 3/9 = 13 1/3 days
Incorrect
Answer a
(x – 5)/25 + x/20 = 1
(4x – 20 + 5x)/100 = 1
9x – 20 = 100
9x = 120
X = 120/9 = 13 3/9 = 13 1/3 days
Question 14 of 20
14. Question
Three years hence, the ratio of Karthi and Janvi will be 7:5. The age of Karthi two years hence is equal to two times of age of Janvi, 5 years ago. What is the present age of Karthi?
Correct
Answer c
Three years hence, the ratio of Karthi and Janvi = 7:5(7x, 5x)
Present age of Karthi and Janvi = 7x – 3, 5x – 3
According to the question,
7x – 1 = 2*(5x – 8)
7x – 1 = 10x – 16
3x = 15
X = 5
The present age of Karthi = 7x – 3 = 35 – 3 = 32 years
Incorrect
Answer c
Three years hence, the ratio of Karthi and Janvi = 7:5(7x, 5x)
Present age of Karthi and Janvi = 7x – 3, 5x – 3
According to the question,
7x – 1 = 2*(5x – 8)
7x – 1 = 10x – 16
3x = 15
X = 5
The present age of Karthi = 7x – 3 = 35 – 3 = 32 years
Question 15 of 20
15. Question
250 m long train crosses a pole in 12 sec and the same train crosses a bridge in 15 sec. Find the length of the bridge?
Correct
Answer c
According to the question,
Speed equal, so,
250/12 = (250+B.L)/15 (Here B.L is Bridge Length)
1250 = 1000 +4 B.L
4B.L = 1250 – 1000
B.L = 250/4 = 125/2= 62.5 m
Incorrect
Answer c
According to the question,
Speed equal, so,
250/12 = (250+B.L)/15 (Here B.L is Bridge Length)
1250 = 1000 +4 B.L
4B.L = 1250 – 1000
B.L = 250/4 = 125/2= 62.5 m

Answers:
1). Answer b
(89/2800)*12768 + (4/9)*34785 + 729 = 4x
405.84 + 15460 + 729 = 4x
16594.84 = 4x
X = 16594.84/4 = 4148.71
2). Answer c
12 7/12 + 8 5/6 – 5 ½ – 7 ¼ – 3 ¾ = x
X = (12 + 8 – 5 – 7 – 3) (7/12 + 5/6 – ½ – ¼ – ¾)
X = 5 [(7 + 10 – 6 – 3 – 9)/12]
X = 5 (-1/12) = (60 – 1)/12 = 59/12
X = 4 11/12
3). Answer a
(5/17)*(408/75)*(124/248)*32736 = (30/100)*x
X = 654720*(4/30)
X = 87296
4). Answer d
(1256/4)*(138/3) = (810/3) + x
314*46 = 270 + x
14444 – 270 = x
X = 14174
5). Answer c
156 – 224 + (75/100)*1500 = x
X = 156 – 224 + 1125
X = 1057
