• A. 167
• B. 157
• C. 147
• D. 137

Answer 1

The correct option is C

147

By long division method

Since we are getting a remainder, we must add a number to 55078 such the the resulting number is the the square of 235. (one more than the quotient)

${235}^2=55225$

So, number which we need to add is 55225 - 55078

= 147
