4250
Option C
350% of ? ÷50+248=591 350 × ?/100 × 1/50 = 343
=>? = 4900

2. 25 × 3.25 + 50.4 ÷ 24 = ?
85.54
77.23
72.44
83.35
80.12
Option D
25 × 3.25 + 50.4 ÷ 24 = ?

3. [(15.5 × 28) ÷ 16 – 1230 ÷ 240] = ? × 5
6.3
5.9
2.5
3.8
4.4
Option E
[(15.5 × 28) ÷ 16 – 1230 ÷ 240] = ? × 5
=> 434 ÷ 16 – 5.125 = ? × 5
=> 27.125 – 5.125 = ? × 5
=> 22 = ? × 5
=>? = 22/5 = 4.4

4. (? )^2 + (65)^2 = (160)^2 − (90)^2 – 7197
72
78
60
66
81
Option B
(? )^2 + (65)^2 = (160)^2 − (90)^2 − 7191
=> (? )^ 2 = (160)^2 − (90)^2 − 7191 − (65)^2
=> (? )^2 = 25600 − (8100 + 7191 + 4225)
=> (? )^2 = 25600 − 19516 => (? )^2 = 6084
=> (? ) = √6084 = 78

5. 423.62 – 269.21 ÷ (11.9% of 78) = ?
395
333
447
400
425
Option A
423.62 – 269.21 ÷ (11.9% of 78) = ?
=> 425 – 270 ÷ (12% of 80) = ?
=>425 − 270 ÷ ( 12 × 80 100 ) = ?
=>? = 425 – 270 ÷ 10
=> ? = 425 – 27
=> ? = 398 == 395

6. A man bought a piece of land for Rs. 72000. He sold 1/3 of the part at 20% loss and 2/3 of the remaining at 25% profit. At what rate should he sell the remaining portion to earn a 20% profit on the whole land ?

Let he sells the remaining part for Rs. x.
1/3 × 80/100 × 72000 + 2/3 × 2/3 × 125/100 × 72000 + 𝑥 = 120/100 × 72000
=> x = 86400 – 59200
=> x = Rs. 27,200

In one hour, Tank A and B together can effectively fill (1/6−1/12) = 1/12 of the tank
=> In 4 hours Tank A and B can effectively fill = 1/12×4 = 1/3 of the tank.
Time taken to fill the remaining (1−1/3) = 2/3 of the tank
= (2/3)/(1/6) = 4 hours
