correct answer is: d) 1.9

Explanation

Here, the LCM of 1.9, 0.95 and 0.076 is the required least number.
Now,
1.9=1.900
0.95=0.950
0.076=0.076
Let, 1.900=1900\ ,\ 0.950=950\ ,\ 0.076=76
So, the LCM of 1900,950 and 76 is 1900.
\therefore LCM of 1.900, 0.950 and 0.076 is 1.900
\therefore The least number is 1.9
Ans: 1.9 is the least number which when divided by 1.9, 0.95 and 0.076, gives integers as quotients.

This particular math question can also be formulated in the following manner:

1. Finding the minimum integer dividend for evenly dividing by 1.9, 0.95, and 0.076.
