B
666
C
3000
D
6000
       Aptitude       Verbal       GATE 2019       Video-Explanation
Question 3 Explanation: 
Total no. of friends = 10
Gift cost = 10x
When two people are not going to contribute then remaining friends have to pay Rs 150 more.
Two friends contribution = 150 × 8 = 1200
One friend contribution = 600
Ten friends contribution = 6000
Cost of the Gift = 6000

Method-2: There were ten friends decided to buy a gift.
Out of ten members two members are not able to pay their share.
So, two members amount was paid by remaining eight members.
Then the eight members has to pay 150 more, which is 150*8= 1200( two persons share).
One person share= 1200/2=600.
Ten members share= 600*10= 6000.
Price of the gift= 6000.

C
7987
D
63847
       Aptitude       Numerical       GATE 2018       Video-Explanation
Question 17 Explanation: 
Method-I:
Take the LCM of 20, 42, 76 i.e., 7980.
⟹ Remainder = 7
⟹ Smallest number divisible by 20 (or) 42 (or) 72 which leaves remainder 7 is = 7980 + 7 = 7987
Method-II:
Option I:
3047 – 7 = 3040
3040 not divisible by 42
Option II:
6040 not divisible by 42
Option III:
7980 divisible by 20, 42, 76
Option IV:
63840 divisible by 20, 42, 76
→ Smallest (7980, 63840) = 7980
→ 7980 + remainder 7 = 7987

A
-1
B
1/pqr
C
1
D
pqr
       Aptitude       Numerical       GATE 2018       Video-Explanation
Question 18 Explanation: 
pqr≠0
→ p-x = 1/q ⟹ 1/px = 1/q
⟹ q = px
⟹ log q = log px
⟹ x log p = log q
⟹ x = log q/ log p
→ q-y = 1/r ⟹ 1/qy = 1/r
⟹ qy = r
⟹ y log q = log r
⟹ y = log r/ log q
→ r-z = 1/p ⟹ 1/rz = 1/p
⟹ p = rz
⟹ log rz = log p
⟹ z log r = log p
⟹ z = log p/ log r
XYZ = log q/ log p * log r/ log q * log p/ log r =1
Question 19

In the figure below, ∠DEC + ∠BFC is equal to

A
∠BCD – ∠BAD
B
∠BAD + ∠BCF
C
∠BAD + ∠BCD
D
∠CBA + ADC
       Aptitude       Numerical       GATE 2018       Video-Explanation
Question 19 Explanation: 

→ ∠1 = ∠5 + ∠4 ………(i)
According to triangular property:
Angle of exterior = sum of interior angles
→ ∠4 = ∠3 + ∠2 ……….(ii)
By substituting (ii) in (i)
→ ∠1 = ∠5 + ∠3 + ∠2
→ ∠1 = ∠BCD
∠2 = ∠BAD
→ ∠BCD – ∠BAD = ∠1 – ∠2
= ∠5 + ∠3 + ∠2 – ∠2
= ∠ 5 + ∠3
= ∠DEC + ∠BFC
Question 20

B
1:1
C
3:2
D
2:1
       Aptitude       Numerical       GATE 2018       Video-Explanation
Question 20 Explanation: 
Let us consider total no. of guests = 100
→ 60% invited guests are males i.e., 60 males
→ 40% invited guests are females i.e., 40 females
→ 80% invited guests are attended i.e., total guests attended to a party = 80
→ All the invited females are attended then remaining people are males = 80 – 40 = 40 males
⇒ 40 males : 40 females
⇒ 1 : 1

B
2,00,000
C
1,75,000
D
1,51,000
       Aptitude       Numerical       GATE 2018       Video-Explanation
Question 21 Explanation: 
Male senior citizen’s gift = Rs.750
Female senior citizen’s gift = Rs. 1000
No. of males = a say
No. of females = b say
Altogether no. of persons eligible for gift = 300
i.e., a+b = 300
Total amount be given = (8x/9 × 750) + (2y/3 × 1000)
= (2000x/3) + (2000y/3)
= 2000/3 (x+y)
= 2000/3 (300)
= 2,00,000

3C2 / 10C2 * 4C2 / 10C2 * 3C2 / 10C2
⇒ 3/45 + 6/45 + 3/45
⇒ 12/45
= 4/15

Question 47

A cube is built using 64 cubic blocks of side one unit. After it is built, one cubic block is removed from every corner of the cube. The resulting surface area of the body (in square units) after the removal is __________.

A
56
B
64
C
72
D
96
       Aptitude       Numerical       GATE 2016 [Set-1]       Video-Explanation
Question 47 Explanation: 
64 cubic blocks are used to make the cube
⇒ Side of cube = 4
Surface area of cube = 6s2 = 6 × 42 = 96
Each corner block is associated with three faces of cube.
When they are removed, three new faces are exposed. Thus there appears no net change in the exposed surface area.
Hence, Surface area = 96

       Aptitude       Numerical       GATE 2016 [Set-1]       Video-Explanation
Question 48 Explanation: 
Revenue from Elegance = (27300 + 25222 + 28976 + 21012) × 48 = Rs. 4920480
Revenue from Smooth = (20009 + 19392 + 22429 + 18229) × 63 = Rs. 5043717
Revenue from Soft = (17602 + 18445 + 19544 + 16595) × 78 = Rs.5630508
Revenue from Executive = (9999 + 8942 + 10234 + 10109) × 173 = Rs. 6796132
Clearly, Executive contributes the greatest fraction to the revenue of the company as the revenue from it is the highest.
