In a two-digit number, if it is known that its unit\'s digit exceeds its ten\'s digit by 2 and that the product of the given number and the sum of its digits is equal to 144,then the number is
Detailed Solution for RRB Group D Mock Test - 8 - Question 60 Let the ten's digit be x
Then, unit's digit = x + 2
Number = 10x + (x + 2) = 11x + 2
Sum of digits = x + (x + 2) = 2x + 2
∴ (11x + 2)(2x + 2) = 144
⇒ 22x2 + 26x - 140 = 0
⇒ 11x2 + 13x - 70 = 0
⇒ (x - 2)(11x + 35) = 0
⇒ x = 2
Hence, required number = 11x + 2 = 24.

RRB Group D Mock Test - 8 - Question 87

A is 30% more efficient than B. How much time will they, working together, take to complete a job which A alone could have done in 23 days?

Detailed Solution for RRB Group D Mock Test - 8 - Question 87

Ratio of times taken by A and B = 100 : 130 = 10 : 13
Suppose B takes x days to do the work
Then, 10 : 13 :: 23 : x
⇒ x = ( 23 x 13/10 )
⇒ x = 299 10
A's 1 day's work = 1/23 :
B's 1 day's work = 10/299
(A + B)'s 1 day's work = ( 1/23 + 10/299 ) = 23/299 = 1/13
Therefore, A and B together can complete the work in 13 days

RRB Group D Mock Test - 8 - Question 88

Trains, A and B are travelling on the same route heading towards the same destination. Train B has already covered a distance of 220 km before train A started. The two trains meet each other 11 hours after the start of train A. Had the trains been travelling towards each other (from a distance of 220 km), they would have met after one hour. What is the speed of train B in km/hr?

Detailed Solution for RRB Group D Mock Test - 8 - Question 88

Let the speed of train A = x
and the speed of train B = y
⇒ Relative speed (same direction) = (x + y) kmph
and relative speed (opp. direction) = (x - y) kmph
⇒ 1(x - y) = 220] x 11
11(x + y) = 220
⇒ 11x - 11y = 2420 .....(1)
11x + 11y = 220 .....(2)
Solving equation (1) and (2) we get
22x = 2640
⇒ x = 120 kmph
⇒ y = 220 - 120 = 100 kmph

RRB Group D Mock Test - 8 - Question 89
Below are the statements followed by four conclusions numbered I,II,III and IV. You have to consider the statements and the following conclusions and decide which of the conclusion(s) follows the statement(s).

b. No pen is a bulb.
c. Some bulbs are fans
Conclusion:
I.Some pens are tubelights.
II.No pens are tubelights.
III. Some tubelights are fans.
IV. All tubelights are fans.
Detailed Solution for RRB Group D Mock Test - 8 - Question 89 Some bulbs are fans + All fans are tube lights = Some bulbs are tube lights ....
(a) [I + A = I]. Now, statement (2) + (a) gives:
Some tube lights are not pens
Hence conclusions I and II can’t be established
III follows from first statement on conversion
But IV does not. But I and II make a complementary pair [I-E pair]
Hence either I or II follows
