Solution
The correct option is A 15.377
The four numbers given are 15.377, 16.379, 15.396, and 15.378.
Let's analyse these numbers.
Three numbers have 15 before the decimal point, while one of them has 16. So, 16.379 is not the smallest.
If you look at the tenth place (after the decimal), all four numbers have the number 3.
If you look at the hundredth place(after the decimal) of the remaining three numbers, Two of them have 7 and one has 9. So, 15.396 is not the smallest.
But, at the thousandth place(after the decimal) of the remaining two numbers we have 7 and 8. of which 7 is the smallest.
