Answers :
Direction (1-5):
Scheme A=>
No. of offices in town P = ¾ * No. of offices in town Q under scheme B — (i)
No. of offices in town R = 19/24 * No. of offices in town R under scheme C — (ii)
Total no. of offices in town P under scheme A = Total no. of offices in town R under scheme A — (iii)
Total number of offices under scheme A = 1355 — (iv)
Scheme B =>
Total number of office under scheme B = 930
No. of offices in town Q = No. of offices in town P and R together – 170
No. of offices in town P and R together = n
=> n + (n – 170) = 930
=> n = 550 = No. of offices in town P and R together
Hence the No. of offices in town Q under scheme B = 550 – 170 = 380
From (i), No. of offices in town P under scheme A = ¾ * 380 = 285
From (iii), Total no. of offices in town R under scheme A = 285
From (ii), No. of offices in town R = 19/24 * No. of offices in town R under scheme C
=> No. of offices in town R under scheme C = 24/19 * 285 = 360
From (iv), No. of offices in town Q under scheme A = 1355 – 285 – 285 = 785
No. of offices in town P under scheme B= 2/3 * No. of offices in town P under scheme C — (v)
Scheme C =>
No. of offices under scheme C = 29/31 * No. of offices under scheme B.
=>No. of offices under scheme C = 29/31 * 930 = 870
No. of office in town R under scheme C = 10 + No. of office in town R under scheme B.
Hence, No. of office in town R under scheme B = 360 – 10 = 350
No. of offices in town P under scheme B = 930 – 380 – 350 = 200
From (v), No. of offices in town P under scheme C = 3/2 * 200 = 300
No. of offices in town Q under scheme C = 870 – 300 – 360 = 210
1) Answer: B
Offices in town Q under scheme B = 150/100 * 380 = 570
Offices in town R under scheme C = 25/100 * 360 = 90
Total number of offices in 2020 for town Q under scheme B and offices for town R under scheme C = 570 + 90 = 660
From the given option, 660 offices obtained only from option B.
2) Answer: D
In Town X, the number of offices established under scheme A = 120/100 * No. of offices in town R under scheme A
= 120/100 * 285 = 342
In Town X, the number of offices established under scheme B = 80/100 * No. of offices in town Q under scheme B
= 80/100 * 380 = 304
In Town X, the number of offices established under scheme C = 840 – 342 – 304 = 194
3) Answer: A
Revenue received from town R under these three schemes = (285 * 10) + (350 * 15) + (360 * 12) = 12420 Crore = 124200 million
4) Answer: C
Average number of offices under scheme B and C for town R and town Q together = (380 + 350 + 210 + 360)/4 = 325
5) Answer: B
Total number of offices under scheme A and B together = 1355 + 930 = 2285
6) Answer: C
Required ratio = 930: 870 = 31: 29
Directions (7-10) :
7) Answer: D
Principal of Ashraf = 4/3 * 30000 = Rs.40000
Rate of interest = 120/100 * 2 = 2.4%
Interest of Ashraf = (40000 * 5 * 2.4)/100 = Rs.4800
8) Answer: C
Amount of Nilan = Rs.26500
Principal = 26500/5 = Rs.5300
n = 2 years
SI = 26500 – 5300 = Rs.21200
r = (SI * 100)/(P * n)
= (21200 * 100)/(5300 * 2) = 200%
9) Answer: A
Principal of Anu = Rs.20000
Principal of Ashok = 130/100 * 20000 = Rs.26000
Amount of Ashok = P * (1 + r/100)n
= 26000 * (1 + 3/100)2
= Rs.27583.4
10) Answer: C
r% = ¾ * 4 = 4%
Let X = Principal
Amount = Principal + SI
=> 26500 = X + (X * 2 * 3)/100
=> X = Rs.25000
