ANSWER KEY:
1. (4) × 6.5, × 5.5, × 4.5, × 3.5, × 2.5
2. (1) × 2 + 2, ÷ 2 + 4, × 2 + 6, ÷ 2 + 8, × 2 + 10
3. (2) × 1 – 3, × 3 – 6, × 5 – 9, × 7 – 12, × 9 – 15
4. (4) a + b + c = 54....... (I)
b + c + d = 48....... (II)
From equation (I) and (II)/ समी. (I) और (II) से
a – d = 6
a – 19 = 6
a = 25
5. (1) Ratio of profit/लाभ में अनुपात = 150000 × 12: 250000 × 12
= 3: 5
Share of B/B का हिस्सा = 160000 × 5/8
= Rs.100000
6. (3) Average speed of car/कार की औसत गति = 
= 81.9 km/hr.
= 81.9 km/hr.
Required distance/अभीष्ट दूरी = 81.9 × 12 = 968.4 km. /किमी.
7. (2) 12M × 6 = (10M + 21W) × 3
24M = 10M + 21W
14M = 21W
2M = 3W
12W = 8M
Required number of days/अभीष्ट दिनों की संख्या = 
= 9 days/दिन
= 9 days/दिन
8. (3) 8.4 × 6.5 + 4.6 × 11.5 = ? ÷ 4
54.6 + 52.9 = ? ÷ 4
107.5 = ? ÷ 4
? = 430
9. (2) 15 
+ 1246 = 
of 4465
+ 1246 = of 4465
15 
+ 1246 = 1786
+ 1246 = 1786
15 
= 1786 – 1246
= 1786 – 1246 
= 
= 36
? = 1296
10. (5) (975 ÷ 78) × (3864 ÷ 46) = ?
12.5 × 84 = ?
? = 1050
