Question 311

DSSSB MTS 2026• General intelligence and Reasoning Ability1

Which two signs should be interchanged to make the below equation mathematically correct?

5 + 6 - 2 × 8 ÷ 4 = 30

  1. AOption (a)

    × and -

  2. BOption (b)
    • and ÷
  3. COption (c)

    × and +

  4. DOption (d)

    ÷ and -

View answer & explanation

Correct answer

Answer: (c)C.

× and +

Why this answer is correct

Given,

5 + 6 - 2 × 8 ÷ 4 = 30

  1. Interchange × and -

5 + 6 × 2 - 8 ÷ 4 = 30

5 + 6 × 2 - 2 = 30

5 + 12 - 2 = 30

17 - 2 = 30

15 ≠ 30

  1. Interchange + and ÷

5 ÷ 6 - 2 × 8 + 4 = 30

0.833 - 2 × 8 + 4 = 30

0.833 - 16 + 4 = 30

4.833 - 16 = 30

11.167 ≠ 30

  1. Interchange × and + 

5 × 6 - 2 + 8 ÷ 4 = 30

30 - 2 + 2 = 30

32 - 2 = 30

30 = 30

  1. Interchanging ÷ and -

5 + 6 ÷ 2 × 8 - 4 = 30

5 + 3 × 8 - 4 = 30

5 + 24 - 4 = 30

29 - 4 = 30

25 ≠ 30

Hence, the correct answer is option 3.

Question 312

DSSSB MTS 2026• General intelligence and Reasoning Ability1

Which day is 10th October, 2027 ?

  1. AOption (a)

    Sunday

  2. BOption (b)

    Monday

  3. COption (c)

    Tuesday

  4. DOption (d)

    Saturday

View answer & explanation

Correct answer

Answer: (a)A.

Sunday

Why this answer is correct

We need to find the day on 10th October 2027,

10.10.2027 = 2026 years + period from 1.1.2027 to 10.10.2027.

Counting number of odd days :

The number of odd days in 2000 years = 0. ( odd days is 0 for every 400 years)

Number of odd days in 26 years = 6 leap years + 20 Ordinary years = 6 × 2 + 20 × 1 = 32 days = 4 weeks + 4 days = 4 odd days.

Number of odd days from 1.1.2027 to 10.10.2027= 31(Jan) + 28(Feb) + 31(March) + 30(April) + 31(May) + 30(June) + 31(July) + 31(Aug) + 30(Sep) + 10(Oct) = 283 days = 40 weeks + 3 days = 3 odd days 

Total number of odd days till 10.10.2027 = 4+3 =7 = 0 odd days.

Therefore, the day on 10th October 2027 is Sunday.

Important Points Here we use odd days as Sunday = 0 , Monday = 1, Tuesday = 2, Wednesday = 3, Thrusday = 4, Friday = 5, and Saturday = 6.

Question 320

DSSSB MTS 2026• General intelligence and Reasoning Ability1

Khan 's age after 15 years will be five times his age 5 years back. What is the present age of Khan?

  1. AOption (a)

    15 years

  2. BOption (b)

    5 years

  3. COption (c)

    20 years

  4. DOption (d)

    10 years

View answer & explanation

Correct answer

Answer: (d)D.

10 years

Why this answer is correct

Let us consider Khan's present age is - x years

After 15 years Khan's age will be - (x + 15)

Khan's present age to 5 years back age will be - (x - 5) years

From given data - 

x + 15 = 5 × ( x - 5)

x + 15 = 5x - 25

-4x = - 40

x = 10

Thus, Khan's present age is x = 10 years

Hence, '10 years' is the correct answer.
