a) 77.5

b) 79.5

c) 82.5.

d) 87.5

correct answer is: d) 87.5

#### Explanation

To find the required least number, we need to find the LCM of the given number.

Let,

1.75 = 175

3.5 = 350

6.25 = 625

So, the LCM of Rs 175,350 and 625 is:

v

So that, LCM of Rs 1.75, 3.5 and 6.25 is = 87.50. _{[2 digits after decimal point]}

\therefore The least number that must be divided by 1.75, 3.5, and 6.25 so that the quotients are whole numbers is 87.5. **Ans:** The least number 87.5.
