Q. 71-80 : Read the passage carefully and answer the questions given below :

At last the bomb was made. The site chosen for the test explosion was the

desert region north of Almogordo, two hundred miles from Los Alamos. The

bomb was taken by road and placed on a gaunt tower, one hundred feet high

and weighing thirty-two tons, erected on the top of a hill. The code name for

it was Zero Hill. Zero hour was 5:30 a.m. on Monday, July 16, 1945.

 Oppenheimer himself was at the control centre about nine miles from

Zero Hill. There were a thousand spectators including scientists, government

officials and a strong security force. All not on duty were told to lie down flat,

face and eyes directed towards the ground and with the head away from zero.

 At forty-five seconds to zero hour Dr. Joseph L. Mckibban of California

University set in motion a weird master robot which set other robots in

motion. More than five hundred miles of wiring were used to start the bomb.

Electronic impulses were set in motion and relayed messages; electrons

moved into position. Observers stood with coloured film over their eyes and

heads averted.

 Overhead two B-29 super fortresses hovered, equipped with recording

instruments to test reactions in the atmosphere. Ten seconds before zero

hour a green flare warned the spectators to keep down. Then came the

blinding flash.

 The whole area was suddenly brighter than the brightest day light, and

the bomb was a ball of fire. Even at nine miles, the heat was scorching. Then

came the tremendous roar and the heavy pressure wave, which knocked

down two men outside the control centre. And then came the cloud – the

mushroom cloud, all the colours of the rainbow, ironically beautiful surging

upto over 40,000 feet, over 10,000 feet higher than Everest. The great steel

tower had gone. Lead lined Sherman tanks took scientists towards the huge

sloping crater where it had stood, to see the effects of radiation on the surface

of the earth.

B) cover their eyes with coloured films and keep their head averted.

C) lie down flat, face and eyes directed towards the ground and with the head towards zero.

D) cover their heads with coloured films and eyes closed.

Question 78: B-29 superfortresses and Sherman tanks are used to

A) check the effect of the bomb on the ground and air respectively.

B) check effect of radiation on the ground and air respectively. – Correct

C) check effect of radiation in the air and ground respectively.

D) check the effect of the bomb on the great steel tower.

Explanation: B-29s were "equipped with recording instruments to test reactions in the atmosphere" and Sherman tanks "took scientists towards the huge sloping crater... to see the effects of radiation on the surface of the earth".

Question 79: The beauty of the mushroom cloud is ironical because

A) It knocked down two men outside the control centre.

B) Of the devastating nature of the bomb.– Correct

C) The bomb destroyed the steel tower.

Question 81: The value of 20 × 45 + 0.04 + 0.64 is

B) 31

C) 36 – Correct

C) -1/3

D) -2/3– Correct

Explanation: Let x = 2k, y = 3k. Then (3x + 5y)/(3x - 5y) = (6k + 15k)/(6k - 15k) = 21k/(-9k) = -7/3, and (6x + 4y)/(6x - y) = (12k + 12k)/(12k - 3k) = 24k/9k = 8/3. So -7/3 + 8/3 = 1/3, but the answer is -2/3.

Question 83: If the sum of five consecutive numbers is 190, then the lowest number amongst them is

A) 40

B) 19

C) 38

D) 36– Correct

Explanation: Let the numbers be n, n+1, n+2, n+3, n+4. Sum = 5n + 10 = 190, so 5n = 180, n = 36.

Question 84: The least number by which 2450 must be multiplied to make it a perfect square, is

Question 85: If the price of sugar increases by 20%, by what percentage should a household reduce its consumption of sugar so that the budget remains the same ?

A) 13⅔%

B) 14⅔%

C) 15⅔%

D) 16⅔% – Correct

Question 86: p, q, r are three numbers such that the LCM of p and q is q and the LCM of q and r is r. The LCM of p, q and r will be

A) q

B) r – Correct

C) qr

A) 120°

B) 140°

C) 144° – Correct

D) 145°

Explanation: Let angles be x, 3x, 4x, 7x. Sum = 15x = 360°, so x = 24°. Largest = 7x = 168°, smallest = x = 24°. Difference = 144°.
