Question

Social science books were sold in a school for $ 15026.75. If 100 books were sold, what is the price of one book?

• A. Rs 150.2675
  
• B. Rs 1502.675
  
• C. Rs 150.2675
  
• D. Rs 15.2675
  

Answer 1

The correct option is A Rs 150.2675


Number of books sold = 100
Total money earned by selling = $\$$ 15026.75
Cost of 1 book $=\frac{15026.75}{100}\$$

$15026.75÷100$ is division of a decimal number by the power of 10.

• To divide a decimal by the power of ten, simply move the decimal point.
• For each zero in the power of 10, move the decimal point one place to the left.

Since there are two zeros in 100, move the decimal point two place to the left.

Hence, cost of one book is $ 150.2675
