View answer & explanation

Correct answer

Answer: (b)B.

77

Why this answer is correct

The Correct answer is Option 2. 

Key Points

Convert the expression: 175 ÷ 25 + 5 × 20 − 3 × 10

Apply BODMAS:

175 ÷ 25 = 7

5 × 20 = 100

3 × 10 = 30

So, 

7 + 100 − 30 = 77.

Hence the Correct answer is Option 2.

  2. BOption (b)

    10, 50

  3. COption (c)

    9,45 

  4. DOption (d)

    9, 50

View answer & explanation

Correct answer

Answer: (d)D.

9, 50

Why this answer is correct

The Correct answer is Option 4. 

Key Points

“In 4 years Rahul will be 31” ⇒ Rahul now = 31 − 4 = 27.

“Rahul is 3 times Seema” ⇒ Seema = 27 ÷ 3 = 9.

“4 years ago, Laxmi was twice Rahul”

Rahul 4 years ago =  27 − 4 = 23.

Laxmi 4 years ago =  2 × 23 = 46.

So Laxmi now = 46 + 4 = 50.

Hence the Correct answer is Option 4.

Hence the Correct answer is Option 1.
