Solutions

S1. Ans.(d)
Sol. By trail and error method, (1), (2) and (3) are not perfect squares. 1024 = 32 × 32 = 32².

S2. Ans.(c)
Sol. ATQ.
Difference in hour of algebra and modern maths
= (9 – 4) = 5%
So, 100% of hour = 500
5% of hour=500/100×5=25

S3. Ans.(c)
Sol. Given that
6% of geometry = 36 hour
1% hour = 6 hour
So,
Remaining 1/4 hour arithmetic
Time taken to teach topic of ratio =1/4×46×6 = 69

S4. Ans.(d)
Sol. Given that
DI & modern maths = 8 + 4 = 12%
12% hour =96
1% hour = 8 hour
So, no. system & Geometry = 23 + 6 = 29%
Req. hour = 29 × 8 = 232

S5. Ans.(c)
Sol. Except arithmetic 10% =10% of 54 = 5.4
So, ⇒ 5.4%
So, required angle =360/100×5.4=19.44

S6. Ans.(c)
Sol. Total no. between 700 & 950 = 250
⇒ divisible by 3 → 702 ……948 = 83
⇒ divisible by 7 → 700 ……945 = 36
LCM of 3, 7 = 21
⇒ divisible by 21= 714 ………945 = 12
So, divisible by 3 & 7 = 83 + 36 – 12 = 107
So, which are neither divisible by 3 nor 7 is
= 251 – 107 = 144

S7. Ans.(d)
Sol.
⇒ So, work done by A & B in 3 days
= 3 × (5 + 4) = 27
Percent of total work completed = 27/100 X100 = 27 %

S8. Ans.(b)
Sol. Area of trapezium
=1/2×(sum of parallel sides)×height
=1/2 (18+24)×12 = 252 m²

S9. Ans.(b)
Sol. Net discount=(50+10-(50×10)/100) = 55%

S10. Ans.(b)
Sol. I bottle = 2 : 5 ⇒ 2 + 5 = 7
II bottle = 3 : 4 ⇒ 3 + 4 = 7
III bottle = 4 : 5 ⇒ 4 + 5 = 9
So, to equalize all quantity- we multiply 9 in I & II bottle and multiply 7 in bottle III.
So, we calculate only water quantity —
= 5 × 9 + 9 × 4 + 7 × 5 = 45 + 36 + 35 = 116
