1. a
2. 2a
3. 3a
4. 4a

Show/Hide Answer

Answer = D - 4a

= b-[b-a-b-{b-2b+a)}+2a]
= b-[-a-{-b+a)}+2a]
= b+a-b+a+2a = 4a

1. 160
2. 175
3. 180
4. 195

Show/Hide Answer

Answer = B - 175
Explanation: Suppose the man works overtime for x hours.
Now, working hours in 4 weeks = (5 x 8 x 4) = 160.
Therefore, 160 x 2.40 + x x 3.20 = 432
<=> 3.20x = 432 - 384 = 48
x = 15.
Hence, total hours of work = (160 + 15) = 175.
