Q:

Robert is traveling on his cycle and has calculated to reach point A at 2 p.m. if he travels at 10 km/hr; he will reach there at 12 noon if he travels at 15 km/hr. At what speed must he travel to reach A at 1 p.m. ?

A) 20 kmph B) 18 kmph
C) 12 kmph D) 16 kmph
 
Answer & Explanation Answer: C) 12 kmph

Explanation:

Let the distance traveled be x km.
Then, x/10 - x/15 = 2
3x - 2x = 60 => x = 60 km.
Time taken to travel 60 km at 10 km/hr = 60/10 = 6 hrs.
So, Robert started 6 hours before 2. p.m. i.e., at 8 a.m.
Required speed = 60/5 = 12 kmph.

Q:

Should there be a complete ban on import of sugar by India?

Arguments :

I. No. The production of sugar in India is not sufficient to meet the requirement.

II. No. This will keep the prices of sugar under control as the supply will be adequate.

A) If only argument I is strong B) If only argument II is strong
C) If neither I nor II is strong D) If both I and II are strong
 
Answer & Explanation Answer: D) If both I and II are strong

Explanation:

Import of sugar is directly related with the domestic production of sugar. If import of sugar is banned then it will result in hoarding of sugar besides increase in its prices (due to less supply than the requirement). Hence I is strong. Note that availability of a commodity keeps the prices of the commodity under control. Hence, II is strong.

Q:

The ratio of Karthik’s and Kalyan’s ages is 4: 5. If the difference between the present age of Kalyan and the age of Karthik 5 years hence is 3 years, then what is the total of present ages of Karthik and Kalyan?

A) 56 years B) 62 years
C) 69 years D) 72 years
 
Answer & Explanation Answer: D) 72 years

Explanation:

Let us consider Karthik as K1 and Kalyan as K2.


Given k18+k1 and K2 - (K1 + 5) = 3 

K2 - K1 = 8

K2 = 8 + K1

Now, 

k18+k1= 45

=> K1 = 32 years

Therefore K2 = 40 years.

K1 + K2 = 72 years.
