Q:

50 men can build a tank in 40days, but though they begin the work together, 5 men quit every ten days. The time needed to build the tank is ?

 A) 50 days B) 48 days C) 47.5 days D) 49 days

Explanation:

50 men can build a tank in 40 days
Assume 1 man does 1 unit of work in 1 day
Then the total work is 50×40 = 2000 units

50 men work in the first 10 days and completes 50×10 = 500 units of work
45 men work in the next 10 days and completes 45×10 = 450 units of work
40 men work in the next 10 days and completes 40×10 = 400 units of work
35 men work in the next 10 days and completes 35×10 = 350 units of work
So far 500 + 450 + 400 + 350 = 1700 units of work is completed and

remaining work is 2000 - 1700 = 300 units

30 men work in the next 10 days. In each day, they does 30 units of work.

Therefore, additional days required = $\inline \fn_jvn \small \frac{300}{30}=10$

Thus, total 10+10+10+10+10 = 50 days required.

Q:

In a competitive examination, the average marks for the entire examination was 60 marks. If 20% of the applicants scored 85 marks and 25% scored 95 marks. What was the average marks of the remaining applicants in the examination ?

 A) 60 B) 52 C) 45 D) 35

Explanation:

Let the total applicants be 100
Then, 20% got 85 marks

i.e 20 $\fn_jvn \small \times$ 85 = 1700

and 25% got 95 marks

i.e 25 $\fn_jvn \small \times$ 95 = 2375

Now, the remaining applicants are 55 and let the average marks scored by them be x.

$\therefore$ 2375 + 1700 + 55$\fn_jvn \small \times$ x  =  60 $\fn_jvn \small \times$ 100

$\Rightarrow$ 6000 - 4075 = 55x
$\Rightarrow$ 55x=1925
$\Rightarrow$ x= $\inline \frac{1925}{55}$
$\Rightarrow$x=35.
