Answers with Explanation:-
1.(4) Marks of T = 75
Marks of R = 65
Marks of Q = 110
Marks of P = 85
Marks of U = 120
Maximum marks = 200
Required percentage = 120/200 x 100 = 60%
2.(2)Let the capacity of the tank be 30 litres.
So Pipe A can fill 3 litre/hour, Pipe B can fill 2 litre/hour and Pipe C can empty 1 litre/hour.
Together they can fill = 3 + 2 – 1 = 4 litre/hour
Tank filled in 6 hours = 24 litres
Time to fill the remaining tank by pipe A alone = 6/3 = 2 hours
3.(4)Let the largest and smallest angles be x and 3x. Now
x + 3x + 56 = 180
x = 31
largest angle = 93°.
4.(4)3W = 2M
21 W = 14 M
Let the required number of days be x.
N1 D1 H1 = N2 D2 H2
15 X 21 X 8 = 14 X 6 X x
X = 30 days
5.(2)CP of first item = Rs. 52000
Selling price of second item = 52000 x 0.75 x 1.4
His overall profit = 54600 – 52000 = 2600
6. (4)
Total Students in school = 3600
Number of boys = 4/9 x 3600 = 1600
Number of boys who like hockey = 20% of 1600 = 320
Number of girls = 2000
Number of girls who like hockey = 60% of 2000 = 1200
Number of students who do not like hockey = (1600 – 320) + (2000 – 1200) = 2080
7. (1)
Let the present ages of Sonu and Monu be 7x and 6x. Now
7x – 8 /6x – 8 = 5/4
x = 4
Present age of Monu = 24 years
Monu’s age four years from now = 24 + 4 = 28 years
8. (2)
Let the numbers be x, x + 2 and x + 4. Then
x + (x + 2) + (x + 4) = x + 20
x = 7
So the middle number is 9.
9. (3)
The ratio of their investments = 24000 x 12: 31000 x 8 : 40000 x 6 = 36 : 31:30
Since the ratio of investment is also the ratio of profit,
C’s share = 30/97 x 12028 = 3720
10. (2)
2 M x 6 = 2 W x 9 = 3 C x 8
2 M = 3 W = 4 C
The ratio of efficiency of man, woman and children = 1/2: 1/3: 1/4 = 6: 4: 3
Let the work done by a man, a woman and a children in one day be 6 units, 4 units and 3 units respectively.
So the total work to be done = 2x6x6 = 72 units
Work done by 3 women and 4 children in one day = 3 x 4 + 4x 3 = 24 units
Remaining work = 72 – 24 = 48 units
Number of men required to complete the remaining work in one day = 48/6 = 8
