Option 2: 90.8 km/hr
Option 3: 92.8 km/hr
Option 4: 88.6 km/hr
Correct Answer: 92.8 km/hr
Solution : Time to travel from place X to place Y = 4 hours Speed when travelling from place X to place Y = 80 km/hr Distance from place X to place Y = 4 × 80 = 320 km Time to travel from place Y to place Z = 1 hour Speed when travelling from place Y to place Z = 80 × 180% = 144 km/hr Distance from place Y to place Z = 144 × 1 = 144 km Average speed = $\frac{\text{total distance}}{\text{total time}}$ = $\frac{320+144}{4+1}$ = $\frac{464}{5}$ = 92.8 km/hr Hence, the correct answer is 92.8 km/hr.

Question : Directions: Which one of the given responses would be a meaningful order of the following words? a. Centi b. Deca c. Kilo d. Deci
Option 1: d, a, c, b
Option 2: b, c, d, a
Option 3: a, d, b, c
Option 4: d, b, c, a
Correct Answer: a, d, b, c
Solution : Given: a. Centi b. Deca c. Kilo d. Deci
The arrangement of all the unit prefixes in increasing order is as follows – Here all the words are unit prefixes of International Systems of Units (SI). According to the quantities, Centi comes first as Centi denote 10-2 then Deci as Deci denote 10-1, after that Deca denote 10 and at last Kilo denote 1000. So, Centi→Deci→Deca→Kilo
The order is a, d, b, c. Hence, the third option is correct.
Question : A man sold an item for Rs. 33,750 and incurred a loss of 25%. At what price should he sell the item to have a profit of 25%?
Option 1: Rs. 45,000
Option 2: Rs. 52,450
Option 3: Rs. 40,850
Option 4: Rs. 56,250
Correct Answer: Rs. 56,250
Solution : Given: A man sold an item for Rs. 33,750 and incurred a loss of 25%. Here the selling price (SP) = Rs. 33,750 Loss percentage = 25% So, the cost price (CP) = SP × $\frac{100}{100-\text{loss percentage}}$ = 33750 × $\frac{100}{100-25}$ = 33750 × $\frac{100}{75}$ = Rs. 45,000 Now to have a profit of 25% SP = CP × $\frac{100+\text{profit percentage}}{100}$ = 45000 × $\frac{100+25}{100}$ = 45000 × $\frac{125}{100}$ = Rs. 56,250 Hence, the correct answer is Rs. 56,250.

Question : Directions: In a certain code language, GANT is coded as 126, and PROM is coded as 186. How will GAIL be coded in that language?
Option 1: 63
Option 2: 79
Option 3: 58
Option 4: 87
Correct Answer: 87
Solution : Given: GANT is coded as 126, and PROM is coded as 186.
Add the positional value of the alphabet of the given word and then multiply the resultant by 3. GANT→7 + 1 + 14 + 20 = 42; 42 × 3 = 126 PROM→16 + 18 + 15 + 13 = 62; 62 × 3 = 186 Similarly, GAIL→7 + 1 + 9 + 12 = 29; 29 × 3 = 87
So, GAIL is coded as 87. Hence, the fourth option is correct.

Question : On a certain sum, the simple interest for 2 years is INR 12000. If the sum is INR 12000, then what will be the compound interest (compounding annually) on the same sum at the same rate of interest for the first 3 years?
Option 1: INR 29250
Option 2: INR 29300
Option 3: INR 28500
Option 4: INR 22750
Correct Answer: INR 28500
Solution : Sum, $P$ = INR 12000 Simple interest, SI = INR 12000 Term, $n$ = 2 years Let $R$ be the interest rate. Simple interest = $\frac{\text{Principal × term × Rate}}{100}$ ⇒ $12000 = \frac{12000 × 2 × R}{100}$ ⇒ $R = \frac{100}{2} = 50$% Term, $n$ = 3 years When compounded annually, Compound interest = $P(1+\frac{R}{100})^n - P$ = $12000(1+\frac{50}{100})^3 - 12000$ = $12000(1+\frac{1}{2})^3 - 12000$ = $12000(\frac{3}{2})^3 - 12000$ = $12000(\frac{27}{8} - 1)$ = $12000×\frac{19}{8}$ = $28500$ Hence, the correct answer is INR 28500.
