Q:

The length of a class room floor exceeds its breadth by 25 m. The area of the floor remains unchanged when the length is decreased by 10 m but the breadth is increased by 8 m. The area of the floor is

A) 5100 sq.m	B) 4870 sq.m
C) 4987 sq.m	D) 4442 sq.m

Answer & Explanation Answer: A) 5100 sq.m

Explanation:

Let the breadth of floor be 'b' m.

Then, length of the floor is 'l = (b + 25)'

Area of the rectangular floor = l x b = (b + 25) × b

According to the question,

(b + 15) (b + 8) = (b + 25) × b

$b^{2} + 8 b + 15 b + 120 = b^{2} + 25 b$

2b = 120

b = 60 m.

l = b + 25 = 60 + 25 = 85 m.

Area of the floor = 85 × 60 = 5100 sq.m.

Q:

A train travelling with a speed of 60 km/hr catches another train travelling in the same direction and then leaves it 120m behind in 18 seconds. The speed of the second train is

A) 42 kmph	B) 72 kmph
C) 36 kmph	D) 44 kmph

Answer & Explanation Answer: C) 36 kmph

Explanation:

Given speed of the first train = 60 km/hr = 60 x 5/18 = 50/3 m/s

Let the speed of the second train = x m/s

Then, the difference in the speed is given by

$\frac{50}{3} - x = \frac{120}{18}$

=> x = 10 m/s

=> 10 x 18/5 = 36 km/hr

Q:

Which of the following is the strongest acid?

A) ClCH2COOH	B) BrCH2COOH
C) FCH2COOH	D) ICH2COOH

Answer & Explanation Answer: C) FCH2COOH

Explanation:

FCH₂COOH is the strongest acid out of all.

Since the electron withdrawing inductive effect (-I effect) of the halogens decreases in the order of F>Cl> Br> I , therefore the acidic strength of the α- halo acids decreases in the same order.

FCH₂COOH > ClCH₂COOH > BrCH₂COOH > ICH₂COOH.
