Question : 56 [IBPS-RRB-PO-Prelims-2020]
What is the ratio of the number of members of the sports clubs C and F, who did not participate in the event?
a) 4 : 5
b) 3 : 4
c) 5 : 9
d) 8 : 9
e) 5 : 3
Answer »Answer: (d)
The number of members of sports club C, who did not participate in the event
= (100 – 25)% of 4800 = 3600
The number of members of sports club F, who did not participate in the event
= (100 – 40)% of 6750 = 4050
Hence, the required ratio = 3600 : 4050
= 8 : 9
Question : 57 [IBPS-RRB-PO-Prelims-2020]
Number of members of the sports club A, who did not participate in the event is what percent more/less than that of sports club D?
a) 40%
b) 60%
c) 28%
d) 35%
e) 55%
Answer »Answer: (b)
The number of members of sports club A, who did not participate in the event
= (100 – 65)% of 4000
= 35% of the 4000 = 1400
The number of members of sports club D, who did not participate in the event
= (100 – 30)% of 5000
= 70% of the 5000 = 3500
Hence, the required percent = $\text"3500 - 1400"/3500$ × 100 = 60%.
Question : 58 [IBPS-RRB-PO-Prelims-2020]
What is the average number of members not participated in the event from the sports clubs A, B, D, E and F?
a) 3990
b) 3610
c) 4060
d) 3570
e) 4010
Answer »Answer: (e)
The number of members of sports club A, who did not participate in the event
= (100 – 65)% of 4000
= 35% of the 4000 = 1400
The number of members of sports club B, who did not participate in the event
= (100 – 20)% of 9000 = 7200
The number of members of sports club D, who did not participate in the event
= (100 – 30)% of 5000 = 3500
The number of members of sports club E, who did not participate in the event
= (100 – 35)% of 6000 = 3900
The number of members of sports club F, who did not participate in the event
= (100 – 40)% of 6750 = 4050
Hence, the required average
= $\text"1400 + 7200 + 3500 + 3900 + 4050"/5$ = 4010.
Question : 59 [IBPS-RRB-PO-Prelims-2020]
What is the difference of the number of members participated in the event from the sports clubs B and C and the number of members not participated in the event from the sports clubs D and E?
a) 7400
b) 2400
c) 3600
d) 4400
e) 3000
Answer »Answer: (d)
The number of members of sports club B, who participated in the event
= 20% of 9000 = 1800
The number of members of sports club C, who participated in the event
= 25% of 4800 = 1200
The number of members of sports club D, who did not participate in the event
= (100 – 30)% of 5000 = 3500
The number of members of sports club E, who did not participate in the event
= (100 – 35)% of 6000 = 3900
then required difference = (3500 + 3900) – (1800 + 1200)
= 4400.
Question : 60 [IBPS-RRB-PO-Prelims-2020]

b) 420
c) 460
d) 480

Answer »Answer: (b)
The number of members of sports club B, who participated in the event = 20% of 9000 = 1800
The number of members of sports club B, who played Badminton
= 30% of 1800 = 540
