Q 1 - The proportion between the paces of two trains is 7:8. On the off chance that the second prepare keeps running in 5 hours 400 km, the pace of the first prepare is :

Answer : A

Explanation

Let the speed of first train be 7x km/hr.
Then the speed of the second train is 8x km/hr.
But speed of the second train=400/5km/hr=80 km/hr
∴8x=80⇒x=10.
Hence the speed of first train is (7*10) km/hr=70 km/hr.

Q 2 - A commission operators permits a refund of 2% to a financial specialist while the organization pays on interest of 15% on the speculation. What rate of premium does the financial specialist really acquire on his venture?

Q 3 - If 1/ 1+ 1 / 1+ 1/x = 2 then x = ?

Answer : A

Explanation

1/(1+ 1/ (1+1/x)) = 2
⇒ 1/(1+x/(x+1)) = 2
⇒ (x+1)/ (2x+1) = 2
⇒ x+1= 4x+2
⇒ 3x= -1
⇒ x= -1/3

Q 4 - 587 x 999 = y. What is y?

Answer : A

Q 6 - The average age of 80 girls was 20 years, the average age of 20 of them was 22 years and that of another 20 was 24 years. Find the average age of the remaining girls.

Answer : A

Explanation

Total age of remaining 40 girls = (80*20 - 20*22 ? 20*24)
= (1600-440-480)
= 680 years
Therefore average age for the 40 girls = 680/40 = 17 years

Q 7 - If x/4 + y/3= 5/12 and x/2+ y =1, then the estimation of (x+y) is:

Answer : C

Explanation

Given equations are 3x+4y= 5 ...(i) and x+2y =2 ...(ii)
On multiplying (ii) by 3 and subtracting (i) from it, we get 2y = 1 ⇒y = 1/2
Putting y = 1/2 in (ii), we get x+2*1/2 = 2 ⇒x+1= 2 ⇒x =1
∴(x+y ) = (1+1/2 ) = 3/2

Q 8 - The two hands of a clock will be together between h and (h+1) o'clock at

A - (60/11)h minutes past h o' clock

B - (50/11)h minutes past h o' clock

C - (40/11)h minutes past h o' clock

D - (30/11)h minutes past h o' clock

Answer : A

Explanation

At h o' clock, the minutes hand is 5 h minute spaces
behind the hour hand.
The minute hand gains 55 min spaces in 60 mins.

∴ The minute hand will gain 5h minute spaces
in 60/55 * 5h = 60h/11 minutes.

∴ The two hands will be together between
'h' and 'h+1' o' clock at (60/11)h minutes h o' clock.

Part of the tank filled by both in 10 min. = 10*(1/20+1/60)= 40/60 = 2/3
Remaining part = (1-2/3) = 1/3
1/60 part is now filled in 1 min.
1/3 part is now filled in (60*1/3) min. = 20 min.
