$$7986 \div 165 \times 7=?$$

Solution

We need to find the value of $$7986 \div 165 \times 7$$

Note that $$7986 = 3 \times 11 \times 242$$ and $$165 = 3 \times 11 \times 5$$

Hence, the expression is equal to $$242 \div 5 \times 7$$
This equals $$484 \times 7 \div 10 = 3388 \div 10 = 338.8$$

Hence, the correct answer is option (a)
