  4. DOption (d)

    7

View answer & explanation

Correct answer

Answer: (b)B.

10

Why this answer is correct

Logic followed here is.

The digits of the number are rearranged in ascending order (from smallest to largest) from left to right, and then the sum of the first digit from the left and the first digit from the right is calculated.

Original Number: 5218394

Rearranging in Ascending Order: 1234589

First digit from the left = 1

First digit from the right = 9

Sum of these digits = 1 + 9 = 10

Therefore, the sum of the digits which are first from the left and first from the right in the new number is 10.

Hence, the correct answer is "Option 2".

Question 309

DSSSB Assistant Superintendent 2026• General intelligence and Reasoning Ability1

In the following number-pairs, the second number is obtained by applying certain mathematical operations to the first number. Which numbers should replace X and Y so that the pattern followed by the two numbers on the left side of :: is same as that on the right side of :: ?

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its 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.)

X : 105 :: 22 : Y

  1. AOption (a)

    X=35, Y=88

  2. BOption (b)

    X=30, Y=66

  3. COption (c)

    X=30, Y=88

  4. DOption (d)

    X=35, Y=66

View answer & explanation

Correct answer

Answer: (d)D.

X=35, Y=66

Why this answer is correct

The logic followed here is:

Logic: Second Number = First Number × 3

For the given pair X : 105

⇒ X × 3 = 105

⇒ X = 105 ÷ 3

⇒ X = 35

For the pair 22 : Y

⇒ Y = 22 × 3

⇒ Y = 66

Now, let's verify the options:

Option 1: X = 35, Y = 88

⇒ 35 × 3 = 105 

⇒ 22 × 3 = 66 ≠ 88 

Hence, Option 1 is incorrect.

Option 2: X = 30, Y = 66

⇒ 30 × 3 = 90 ≠ 105 

⇒ 22 × 3 = 66 

Hence, Option 2 is incorrect.

Option 3: X = 30, Y = 88

⇒ 30 × 3 = 90 ≠ 105 

⇒ 22 × 3 = 66 ≠ 88 

Hence, Option 3 is incorrect.

Option 4: X = 35, Y = 66

⇒ 35 × 3 = 105 

⇒ 22 × 3 = 66 

Hence, Option 4 follows the same pattern.

Therefore, the correct values are X = 35 and Y = 66.

Hence, the correct answer is 'Option 4'.
