Q:

A man walks at a speed of 3 kmph. He doubles his speed after reaching exactly half way. He walks for 5 hours in all. What is the total distance travelled by him?

A) 19 km	B) 15 km
C) 12 km	D) 20 km

Answer & Explanation Answer: D) 20 km

Explanation:

Let total distance be 2D.

He walks half distance i.e, (2D/2) = 'D' distance with 3 kmph and

The next 'D' with 6 kmph.

Using formula,

Time = Distance/speed

(D/3) + (D/6) = 5

D =10 ,

Hence, Total distance 2D = 20 kms.

Quantity II: if the side of a triangle is increased by 30% while the height of a triangle is decreased by 20% then find the percentage change in area of the triangle?

A) Quantity I > Quantity II	B) Quantity I ≥ Quantity II
C) Quantity I< Quantity II	D) Quantity I < Quantity II

Answer & Explanation Answer: A) Quantity I > Quantity II

Explanation:

Quantity I= 20% - 10% - (20*10/100) % = +8%

Quantity II= 30% - 20% - (30*20/100)% = +4%

Hence Quantity I > Quantity II
