Question : Two numbers are in the ratio of 2 : 3. If their sum is 125, find the numbers.
Option 1: 50 and 75
Option 2: 24 and 36
Option 3: 20 and 30
Option 4: 32 and 78
Correct Answer: 50 and 75
Solution : Given: The two numbers are in the ratio of 2 : 3. Their sum is 125. Let the numbers be $2x$ and $3x$. As per given condition, $2x+3x=125$ ⇒ $5x=125$ ⇒ $x=\frac{125}{5}$ ⇒ $x=25$ So, the numbers are 50 and 75. Hence, the

Question : Directions: In a certain code language, YEAH is coded as 207, and BULK is coded as 186. What is the code for CORD in that code language?
Option 1: 204
Option 2: 236
Option 3: 208
Option 4: 242
Correct Answer: 204
Solution : Given: YEAH is coded as 207, and BULK is coded as 186.

Question : A double bed is marked at Rs. 7,500. The shopkeeper allows successive discounts of 8%, 5%, and 2% on it. What is the net selling price?
Option 1: Rs. 6,500
Option 2: Rs. 6,000
Option 3: Rs. 6423.90
Option 4: Rs. 6500.50
Correct Answer: Rs. 6423.90
Solution : We know, $\text{Single discount}=(a+b-\frac{a×b}{100}$)% Where $a,b$ are successive discounts. $\therefore$ Single equivalent discount of two successive discounts of 8% and 5% $=8+5- \frac{8×5}{100}=13-0.4=12.6$% Now, the single equivalent discount of two successive discounts of 12.6% and 2% $=12.6+2-\frac{12.6×2}{100}=14.6-0.252=14.348$% The double bed is marked at Rs.
Question : Directions: Select the triad in which the numbers are related in the same way as the numbers of the following triads. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – operations on 13 such as adding/subtracting/multiplying etc, to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.) 6 – 7 – 42 8 –13 –104
Option 1: 5 –15 –125
Option 2: 6 – 4 – 72
Option 3: 12 –11–132
Option 4: 9 – 5 – 24
Correct Answer: 12 –11–132
Solution : Given: 6 – 7 – 42 8 –13 –104
Multiplication of the first two numbers is equivalent to the third number. ⇒ 6 – 7 – 42→6 × 7 = 42 ⇒ 8 –13 –104→8 × 13 = 104
