Answer 1

Answer:

The number is 1210.Pls see the explanation and mark as brainliest.

Explanation:

Let the no. be x. And when 10 is substracted from X let the new number be y which is divisible by 16.25&75

So, to find such a number (y) we need the LCM of the three numbers.

16=4×4

25=5×5

75=3×5×5

LCM(16,25,75)=4×4×5×5×3

LCM=1200

Now we get y=1200.

But the number x has to be 10 more than y.

So,y+10=x

→y=1210

So, the number is 1210.
