View answer & explanation

Correct answer

Answer: (c)C.

97382

Why this answer is correct

According to the question:

MALE → 2375

⇒ M → 2; A → 3, L → 7; E → 5

    77º

  2. BOption (b)

    85º

  3. COption (c)

    77.5º

  4. DOption (d)

    85.5º

View answer & explanation

Correct answer

Answer: (c)C.

77.5º

Why this answer is correct

The Formula used here is:

Angle = |(11/2) M - 30 H|

Where, M = minutes and H = hours

Here, M = 35 and H = 9

Therefore, we get the angle = |(11/2) M - 30 H|

Angle = |(11/2) × 35 - 30 × 9|

Angle = |192.5 - 270| = |-77.5|

Hence, the correct answer is "77.5⁰".

Question 960

DSSSB Junior Assistant (LDC) 2025• Mental Ability & Reasoning 2

  1. AOption (a)

    10 - 36 × 18 + 7 ÷ 6 = 20

  2. BOption (b)

    15 × 3 ÷ 7 - 4 + 9 = 25

  3. COption (c)

    8 ÷ 9 – 7 + 52 × 13 = 67

  4. DOption (d)

    56 + 9 ÷ 8 - 39 × 13 = 70

View answer & explanation

Correct answer

Answer: (c)C.

8 ÷ 9 – 7 + 52 × 13 = 67

Why this answer is correct

The pattern followed here is,

Symbol+-×÷
Meaning-×÷+

After replacing the symbol with their meaning, we get,

Option 1:

10 × 36 ÷ 18 - 7 + 6

= 10 × 2 - 7 + 6

= 20 - 7 + 6

= 26 - 7

= 19

Option 2:

15 ÷ 3 + 7 × 4 - 9

= 5 + 7 × 4 - 9

= 5 + 28 - 9

= 33 - 9

= 24

Option 3:

8 + 9 × 7 - 52 ÷ 13

= 8 + 9 × 7 - 4

= 8 + 63 - 4

= 71 - 4

= 67

Option 4:

56 - 9 + 8 × 39 ÷ 13

= 56 - 9 + 8 × 3

= 56 - 9 + 24

= 80 - 9

= 71

Hence, ‘8 ÷ 9 – 7 + 52 × 13 = 67’ is the correct answer.
