a) 24 days
b) 32 days
c) 48 days
d) 16 days
e) 36 days
Answer »Answer: (b)
$\text"M1xD1"/\text"W1"=\text"M2xD2"/\text"W2"$
$\text"12x64"/1=\text"16xD2"/\text"2/3"$
D2 = 32
Question : 42 [IBPS-RRB-clerk-2020]
At present, P is 4 years elder than Q. If after 2 years the ratio of the ages of P and Q will be 5 : 4, then what will be the age of Q after 2 years?
a) 8 years
b) 16 years
c) 20 years
d) 24 years
e) 10 years
Answer »Answer: (b)
Let ages of P and Q after 2 years will be 5x years and 4x years respectively
According to question
5x – 4x = 4 ⇒ x = 4
Hence, the age of Q after 2 years = 4x
= 4 × 4
= 16 years.
Question : 43 [IBPS-RRB-clerk-2020]
Two people A and B spend 30% of their income if their total expenditure is Rs. 26400 and the income of A is 20% more than B, what is the income of B?
a) Rs. 40000
b) Rs. 36000
c) Rs. 24000
d) Rs. 30000
e) Rs. 48000
Answer »Answer: (a)
Let the income of B = Rs. 100x,
then the income of A = 100x + 20% of 100x
= Rs. 120x
Total expenditure of A and B = 30% of (100x + 120x)
= 66x
According to question 66x = 26400
⇒ x = $26400/66$ = 400
Hence, the income of B = 100x
= 100 × 400
= Rs. 40000
Question : 44 [IBPS-RRB-clerk-2020]
Two people A and B invest an equal amount in a scheme for t and (t + 4) years respectively. If the ratio of the simple interest earned by A and B is 1 : 2, then what is the value of t?
a) 8
b) 1
c) 2
d) 4
e) 5
Answer »Answer: (d)
Let each of A and B invested Rs. 100 and the rate of interest = 1%, then
Simple interest of A = $\text"100x1xt"/100$
= $t(SI = \text"PRT"/100)$
Simple interest of B = $\text"100x1x(t+4)"/100$
= $(t+4)(SI = \text"PRT"/100)$
According to question =$t/1 = \text"t+4"/2$
⇒ t = 4
Question : 45 [IBPS-RRB-clerk-2020]
A train travelling at the speed of 72 kmph passes a pole in 30 seconds. In how much time will the same train pass the same pole if it is travelling at the speed of 54 kmph?
a) 36 seconds
b) 40 seconds
c) 24 seconds
d) 48 seconds
e) 60 seconds
Answer »Answer: (b)
Let the required time = t seconds, then
72 × 30 = 54 × t (Distance = Speed × Time)
⇒ t = 40
