Solution

## The correct option is B 24.15To find total amount of money spent by John on 7 chocolate bars, we need to find 3.45×7 Consider 3.45 as whole number 345 by shifting decimal point 2 units to the right. 345×7=2415 Now, compensate movement of the decimal point in 3.45 by shifting the decimal point in 2415.0 two units to the left i.e 24.15 ∴ 3.45×7=24.15
