25 Important Previous Year Q&A | HCA Study Material [23 September 2021]_70.1

84. (A)

Let say Number = N

N² + N  = 240

=> N² + N  – 240 = 0

=> N²  + 16N – 15N – 240 = 0

=> N(N + 16) – 15(N + 16) = 0

=> (N + 16)(N – 15) = 0

=> N = -16  or N = 15

Hence Numbers are – 16  and 15

As 15 is in the option , 15 is the correct answer.

85. (A)

= (4-5)-(13-18+2)
= (-1)-(-3)
= -1+3
= 2

86. (D)

Marketed price = Rs.65
Discount. = 15%
= (15/100)*65

95. (C)

The Question asked :
Find the time taken by a 180 m long train running at 54 km/hr to cross a man standing on a platform.

Answer :
Let the time taken to cross the man standing on the platform be = x
We know that :
Speed = Distance / Time
Put the values in the formula, but before, convert 54 km/hr into m/s so that all the quantities are in the same units
54 km/hr =25 Important Previous Year Q&A | HCA Study Material [23 September 2021]_130.1
54 km/hr = 15 m/s
Put this value into the formula :
15 = 180 / x
=》  x = 180 / 15
=》 x = 12 s
Thus, the time taken is 12 seconds

96. (D)

Starting with the first number ‘1’, we move ahead in the way given below:

1 x 2 + 1 = 3

3 x 2 + 1 = 7

7 x 2 + 1 = 15

15 x 2 + 1 = 31

31 x 2 + 1 = 63

63 x 2 + 1 = 127

Therefore 127 is the next number in the series.

97. (A)

The only number between 90 and 100 that has only two factors i.e. 1 and the number itself is 97. Therefore, the sum of prime numbers between 90 and 100 will also be equal to 97. So, the correct answer is “97”.

98. (A)

In the question above option a)-1 is correct .Because negative numbers are smaller than 0 or the whole numbers . We cannot consider -1/2(which is equal to -0.5 ) because -0.5>-1. Therefore the correct answer is -1.

99. (D)

Pipe A can fill a tank in 12 minutes,pipe B in 18 minutes and pipe C can empty the full tank in 36 minutes. If all of them are opend simultaneously, find the time taken to fill the empty tank. The work done by the 3 pipes together in 1 minute =1/12+1/18-4/36=4/36=1/9. So, the empty tank will be filled in 9 minutes.
