What should come in place of * mark in the following equation ?
1 * 5 $ 4 ÷ 148 = 78
Answer & Solution
Correct Answer:
Option
A
Let , $$\frac{1x5y4}{148}$$ = 78
Then,
10000 + 1000x + 500 + 10y + 4 = 148 × 78
⇒ 10000 + 1000x + 500 + 10y + 4 = 11544
⇒ 10000 + 1000x + 500 + 10y + 4 = 10000 + 1000 + 500 + 40 + 4
⇒ 1000x = 1000
⇒ x = 1
Then,
10000 + 1000x + 500 + 10y + 4 = 148 × 78
⇒ 10000 + 1000x + 500 + 10y + 4 = 11544
⇒ 10000 + 1000x + 500 + 10y + 4 = 10000 + 1000 + 500 + 40 + 4
⇒ 1000x = 1000
⇒ x = 1
