What will come in place of question mark ‘?’ in the following question?
1331 × 0.11 × 121 × 11 = (1.1)? × 1100001331 × 0.11 × 121 × 11 = (1.1)? × 110000
Make factors of the terms in the equation
⇒ 11 × 11 × 11 × 0.11 × 11 × 11 × 11 = (1.1)? × 110000
⇒ (1.1)? = 11 × 11 × 11 × 11/100 × 11 × 11 × 11/110000
⇒ (1.1)? = (11)6/(10)6
⇒ (1.1)? = (1.1)6
⇒ ? = 6
