None of these
Ans.- C
Let the number be x. Then , x - 3/5x = 50
x = (50 x 5 ) / 2 = 125
Let the number be x. Then , x - 3/5x = 50
x = (50 x 5 ) / 2 = 125
Q2)-If a number is decreased by 4 and divided by 6 , the result is 8. What would be the result if 2 is subtracted from the number and then it is divided by 5 ?
9 (2/3)
10
10 ( 1/5 )
11 (1/5)
Ans.- B
Let the number be x. Then , ( x -4 ) /6 = 8
x = 52.
(x - 2) / 5 = ( 52 - 2 ) / 5 = 50 / 5 = 10
Let the number be x. Then , ( x -4 ) /6 = 8
x = 52.
(x - 2) / 5 = ( 52 - 2 ) / 5 = 50 / 5 = 10
Q3)-If one-third of one-fourth of a number is 15 , then three-tenth of that number is
35

45
54
Ans.- D
Let the number be x . Then , 1/3 of 1/4 of x = 15
x = 15 x 12 = 180
So , required number = ( 3/10 x 180 ) =54
Let the number be x . Then , 1/3 of 1/4 of x = 15
x = 15 x 12 = 180
So , required number = ( 3/10 x 180 ) =54
Q4)-A number is doubled and 9 is added. If the resultant is trebled, it becomes 75. What is that number ?
3.5
6
8
None of these
Ans.- C
Let the number be x. Then , 3(2x+9)=75
2x + 9 = 25
2x = 16
x = 8
Let the number be x. Then , 3(2x+9)=75
2x + 9 = 25
2x = 16
x = 8
Q5)-Three-fourth of a number is 60 more than its one-third. The number is
84
108
144
None of these
Ans.- C
Let the number be x. Then 3/4 x - 1/3 x =60
5x/12 = 60
x = 144
Let the number be x. Then 3/4 x - 1/3 x =60
5x/12 = 60
x = 144
Q6)-When 24 is subtracted from a number , it reduces to its four-seventh. What is the sum of the digits of that number ?
1
9
11
Data inadequate
Ans.- C
Let the number be x. Then , x - 24 = 4/7x
3/7 x = 24
x = (24 x 7 ) /3 = 56
Sum of the digits = ( 5 + 6 ) =11
Let the number be x. Then , x - 24 = 4/7x
3/7 x = 24
x = (24 x 7 ) /3 = 56
Sum of the digits = ( 5 + 6 ) =11
Q7)-Find the number which when multiplied by 15 is increased by 196.
14
20
26
28
Ans.- A
Let the number be x. Then , 15x - x = 196
14x = 196
x =14
Let the number be x. Then , 15x - x = 196
14x = 196
x =14
Q8)-If a number , when divided by 4 , is reduced by 21, the number is
18
20
28
38
Ans.- C
Let the number be x. Then x/4 = x-21
x = 4x -84
3x =84
x = 28
Let the number be x. Then x/4 = x-21
x = 4x -84
3x =84
x = 28
Q9)-A number whose fifth part increased by 4 is equal to its fourth part diminished by 10 , is
240
260
270
280
Ans.- D
Let the number be x. Then, ( 1/5 x + 4) = ( 1/4 x - 10 )
x/20 = 14
x = 280
Let the number be x. Then, ( 1/5 x + 4) = ( 1/4 x - 10 )
x/20 = 14
x = 280
Q10)-The difference of two numbers is 20 % of the larger number. If the smaller number is 12, the larger one is
15
16
18
20
Ans.- A
Let the larger number be x. Then , x - 12 = 20 % of x
x - x/5 = 12
x = (12 x 5 ) / 4 = 15
Let the larger number be x. Then , x - 12 = 20 % of x
x - x/5 = 12
x = (12 x 5 ) / 4 = 15
