1) Raj while going by bus from home to airport takes 10 minute less than time taken when the bus halts for some time. The average speed is 4 km/hr more than the average speed of the bus when it halts. If the distance from home to airport is 60 km, what is the speed of the bus when it is travelled without any halt ?
A)24
B)46
C)20
D)40
E)18

Explanation: Let the speed of the bus when it halts – X km/hr Speed of the bus when it travelled = (X+4) km/hr According to question, (60/X )- 60/(X+4)=10/60 X=36 Speed of the bus when it travelled (36+4)=40 km/hr Tricks 60= {X * (X+4)*10/60}/4 X=36 Speed of the bus when it travelled (36+4)=40 km/hr

2) Every month Mr Duggabati spends 24 % of his monthly income in paying rent and 30 % on shopping of groceries. Out of the remaining , he invests in fixed deposit and respective ratio of 9:7. If in a year, he deposited a total of Rs 124200 in fixed deposit, how much did he pay as rent in a

Explanation: Let the monthly income of Duggabati = Rs X According to question, 124200= X *(100-24-30)/100 * 9/16 * 12 X=Rs 40000 So Duggabati spent on paying rent in a year = 40000 * 24/100*12= Rs 115200

3) The total time taken by a boat to travel ‘X’km downstream and ‘X-5 ‘ km upstream was 285 Min. If the difference between speed of the boat downstream and upstream is 3 km/hr and the Respective ratio between speed of boat in still water and speed of water current was 9:1, what is the value of ‘X’
A)40.4
B)30
C)20.4
D)34.4
E)36

Explanation: Let the speed of boat in still water = 9V Speed of current = V According to question X/(9V+V) + (X+5)/(9v-V)=285/60 X=34.4 km

A)Rs 600
B)Rs 400
C)Rs 500
D)Rs 540
E)Rs 400

Explanation: Let the cost price of article A = Rs X Cost price of article B= X * 120/100 =6X/5 Marked price of article A= X * (150/100)=3X/2 According to question {(3X/2)*95/100}- {(3x/2) * 91/100=30 X=500

6) Ram’s age after 17 years will be 6 years less than twice his present age. The respective ratio between Vivian’s present age and Amit’s present age is 21 :19 . If Amit’s age 31 years hence will be same as three times Ram’s present age, what will be Vivian’s age 4 years hence ? (in years)
A)44
B)45
C)46
D)48
E)None of these

Explanation: Check option Suppose Vivian’s 4 years hence will be =46 years So present age will 42 Vivian present’s age must be divided by his present ratio 21 So ans 46

7) Jar A has “X’ litre of mixture of apple juice and water in the respective ratio of 5 : 1 and Jar B has “X” litre of mixture of mango Juice and water in the respective ratio of 2 : 1 . 30 litres of mixture was taken from jar A and Jar B each and mixed in jar C .If 12 litres of mixture was taken out from jar C, what was the final quantity of water in Jar C?
