Answer Key-

Q-(1) Sol-(4)

Suppose the worker remained idle for x days. Then,

He worked for (30 – x) days. =35 (30 – x) – 7.5x =710

On solving

x = 8 days

Q-(2) Sol-(3)

Let CP be 100 then MP 120

5% discount =114.

10% discount =108.

Diff 6=21

(CP)

100 = 350.

Then MP=120% of 350=420

Now SP after 20% discount =336.

Loss = 350-336 = Rs14.

Q-(3) Sol-(2)

Total present age of the family (6×25) = 120 yrs

Total age of the family 6 years ago = (150 – 6×5) = 120 years

At that time, Total members in the family = 5

Therefore Average age at that time = 120/5 = 24 yrs.

Q-(4) Sol-(5)

Required answer=7×6×5=210
