Question 20: If E = 10; J = 20 ; O = 30 ; and T = 40, what will be P + E + S + T?
(a) 51
(b) 120
(c) 82
(d) 164
     [2019 : 1 Mark, Set-I]
Answer: (b)

Question 21: A faulty wall clock is known to gain 15 minutes every 24 hours. It is synchronized to the correct time at 9 AM on 11^th July, What will be the correct time to the nearest minute when the clock shows 2 PM on 15^th July of the same year? 
(a) 12:45 PM 
(b) 12:58 PM 
(c) 1:00 PM 
(d) 2:00 PM 
     [2018 : 2 Marks, Set-II]
Answer: (b)
Solution: 9 Am of 11 July of 2 PM on 15th July = 101 hours
 hours of incorrect clock = 24 hours of correct clock

= 24 hours of correct clock
1 hour of IC = 96/97 hours of correct clock

= 99.958 hours of correct clock
= 99 hours + 0.95876 x 60 minutes of correct clock
= 99 hours + 57.525 min.
= 99 hours and approx 58 min.
So, correct time will be
2 PM, 11^th july + (99 hours and 58 minutes)
= 12: 58 PM on 15th July

Question 22: Given that  = 10 for x ≠ y ≠ z, what is the value of the product PQR? 
(a) 0 
(b) 1 
(c) xyz 
(d) 10^xyz
    [2018 : 2 Marks, Set-II]
Answer: (b)
Solution: logP = 10(y - z)
logQ = 10(z - x)
logR = 10(x - y)
logP + logQ + logR = 0
log (PQR) = log 1
PQR = 1

Question 23: The annual average rainfall in a tropical city is 1000 mm. On a particular rainy day (24-hour period), the cumulative rainfall experienced by the city is shown in the graph.

(a) 25,000 
(b) 18,750 
(c) 7,500 
(d) 3,125 
    [2018 : 2 Marks, Set-II]
Answer (c)
Solution: Cumulative rainfall = 300 mm

Area = 50 m²


Question 24: Each of the letters in the figure below represents a unique integer from 1 to 9. The letters are positioned in the figure such that each of (A+B+C), (C+D+E), (E+F+G) and (G+H+K) is equal to 13. Which integer does E represent?

(a) 1
(b) 4
(c) 6
(d) 7
    [2018 : 2 Marks, Set-II]
Answer: (b)
Solution: 
A + B + C= 13 ,..(i)
C + D + E= 13 ...(ii)
E + F + G = 13 ...(iii)
G + H + K= 13 ...(iv)
Adding [(i) + (ii) + (iii) + (iv)]
A + B + C +D + E + F+ G + H + K+ (C + E + G) = 13 x 4 = 52 ...(v)
Also A, B, C, D, E, F, G, H& K represents natural numbers from (1 to 9)
There sum will be given by
Substituting (iv) C + E + G - 7 ,..(vi)
Only possibly for sum 7 will be (1, 2, 4)
Now, C + E cannot be (1 and 2)
As eq. (ii) is C + D + E = 13
Now, D will become equal to 10 (which is not possible because digits 1 to 9 given)

If C = H from eq. (vi) C + E + G = 7
Now, E + G = 3
(Not possible in eq. (iii) E + F + G = 10,
F - 10 which is not possible)
So from eq. (vii) only possibility remains is E = H.

Question 25: In manufacturing industries, loss is usually taken to be proportional to the square of the deviation from a target. If the loss is Rs. 4900 for a deviation of 7 units, what would be the loss in Rupees for a deviation of 4 units from the target? 
(a) 400 
(b) 1200 
(c) 1600 
(d) 2800
    [2018 : 2 Marks, Set-H]
Answer: (c)
Solution: Loss = kd² 

For duration of 7 units
4900 = k (7)² ⇒ k = 100
Loss = kd²   

For duration of 4 units
= k(4)² ⇒ 16k = 1600

Question 26: What of the following function(s) in an accurate description of the graph for the range(s) indicated?

(a) y = 2x + 4 for -3 < x < ~ 1 
(b) y = |x - 1| for -1 < x < 2 
(c) y = | |x | - 1| for -1 < x < 2 
(d) y = 1 for 2 < x < 3
(a) (i), (ii) and (iii) only 
(b) (i), (ii) and (iv) only 
(c) (i) and (iv) only 
(d) (ii) and (iv) only
     [2018 : 2 Marks, Set-I]
Anwser: (b)
Solution: Put value and verify
(i) y = 2x + 4 is true in -3 < x < - 1
On putting x = -3, y = -2 and x = -2,
y = 0 and x = -1, y = 2
(ii) y = |x - 1| is also true (x = -1, y = 2), (x = 0, y = 1) and (x = 1, y = 0)
(iv) y = 1 in (2 < x < 3) always true
(i), (ii) and (iv) are true.

Question 27: The price of a wire made of a superalloy material is proportional to the square of its length. The price of 10 m length of the wire is Rs. 1600. What would be the total price (in Rs.) of two wires of lengths 4 m and 6 m? 
(a) 768 
(b) 832 
(c) 1440 
(d) 1600 
    [2018 : 2 Marks, Set-I]
Answer: (b)
Solution: C ∝ W²
C = kW² 
⇒ C= k(10)² = 100k = 1600
⇒ k = 16
C1 = k(4)² = 16k
C₂ = k(6)² = 36k
Now total cost = 52k = 52 x 16 = 832

(a) 4 
(b) 5 
(c) 6 
(d) 9
Answer: (b)
Solution: 

Any of A, B, C, D, E, F, G cannot be 5.

(a) 48 
(b) 52 
(c) 60 
(d) 108
     [2018 : 2 Marks, Set-I]
Answer: 12.5%x + 10%x = 108
x  =108/22.5
