Mathematics
Ans.51(C) First find the standard deviation
Mean = (2+4+7+8+15+18)/6 = 54/6 =9
Now (2-9)2 , (4-9)2, (7-9)2,(8-9)2,(15-
9)2 ,(18-9)2
49, 25, 4, 1, 36, 81
Mean of above data
= (49+25 +4 + 1+ 36 + 81)/6
= 196/6
= 32.66
Standard deviation = √32.66
Variance = (Standard deviation)2
=(√32.66)2=32.66
Ans.52(B) Numbers be = 3 x 13, 2 x 13
= 39, 26

(x-y) (x+y)= 13
x+y=13
x-y= 1
x=7
y=6
Ans.55(B) Efficiency Ratio Abhishek : Bablu
= 100 : 130 =10 : 13
Time Ratio Abhishek : Bablu = 13 : 10
13 x = 65
x= 5 days

Ans.56(A) The mean is the usual average. The median is the middle value of the series of number.
The mode is the number that is repeated
more often than any other in the series.
Mode = mean – 3(Mean – Median)
1 = Mean – 3 (3)
Mean = 10
Ans.57(A) If the value of the n = mode is equal to the
value of the median and the mean then we
call it as symmetrical data set.
Mode = 3 median- 2mean
Median = 6
Mean = 7
Mode = 3 (6) – 2 (7)
Mode = 18 – 14 = 4
Ans.59(C) If external dimensions are given and the thickness is given then the corresponding internal dimensions are external
dimensions minus the twice of thickness. Hence
Internal length is 37.5 – 2 × 1.25 = 35
Similarly breath is 22.5 – 2 × 1.25 = 20
and height is 15.
Volume = Length × Width × Height
Volume = 35 × 20 × 15 = 10500
Since it is half filled = 10500/2 = 5250

Ans.62(A) S1 = 5 kmph S2 = 4 kmph
T1 = 6 hours T2 = 12 hours
D1 = Time × Speed = 5 × 6 = 30 Km
D2 = 12 × 4 = 48 km
Total Distance = 30 + 48 = 78 km
Average Speed = Total Distance/ Total time
= 78 / 18 = 4.3 kmph
Ans.63(A) Distance = 200 m
Speed = 54 kmph
Speed = 54 km/hr = 54 × (5/18) = 15 m/s
Relative speed = 15 – 5 = 10m/s
Time = 200/10 = 20 sec
Ans.64(A) Let both of them working together will take x hrs
A will take x+8 hrs
B will take x+18 hrs

= √(18×8)
= 12 hrs.
Ans.65(A) A – 8 days
B – 8×3/4= 6 days
Let the total work be 24 units then
efficiency of A and B will be 3 and 4
hence total efficiency = 7
Days = Total work/ Efficiency = 24/7 days
Ans.66(C) Let the person brings 48 candies of first type and 48 candies of 2nd type
Total cost of both the candies
= 48/6 + 48/4 = Rs 20
But if sells them at 8 per rupee then selling
price = 96/8 = 12
Loss = 20 – 12 = Rs 8
But in question loss is Rs 24
Which is 3 times the price hence he must have bought 3 times the quantity of candies.
96×3=288
Ans.67(C) 4M + 3P = 113 ———— (1)
7M+4P = 184 ———— (2)

Cost of Pencil = Rs. 11
Hence 2 markers and 1 pencil cost Rs. 51
Ans.68(A) Soln
Pinku : Rinku ( 10 yrs ago) — 6 : 7
After 6 years ratio ——–10 : 11
Let 6 yrs after Pinku and Rinku age be 10x and 11x then
10x – 16/ (11x – 16) = 6/7 x = 4
Age of Rinku’s after 6 yrs is 44 and after 9 yrs it will be 44 + 3 = 47 year
Ans.69(A) Let income of A and B be 15x and 28x Then income – savings = expenditure Hence savings of A and B are 20000 and 40000

Upon solving x = 15000
Hence A = 225000
Ans.70(A) Population in 2019 = 25270
Population in 2017 =
x (5.56/100) × (5.56/100) = 25270
x = 25270 × (18/19 × 18/19) = 22680

Ans.84(C) Since the ratio between the 2 numbers cannot be reduced further hence. The two numbers must be 3×31 and 3×41
and the LCM would be 3×31×41 = 3813
Ans.85(D) HCF means a factor which is common to all the numbers and is of highest order. Hence in the above numbers 4 is the highest common factor and d is not included because it is not common and is not contained in the 1st number.
