2994 ÷ 14.5=206.48 and 29.94 ÷ 1.45 = 20.6 above the four options are not correct.
If the answer is 2994 ÷ 14.5 = 172 without any calculation based on the decimal value the answer is 17.2 is correct otherwise, the proper calculation the answer is not correct.

If 2994/14.5 = 172 then 29.94/1.45 = ?
We can write 29.94/1.45 as 2994/145 (by mul with 10 both numerator and denominator).
Then, 2994/145 can be written as 2994/(14.5 x 10) or (2994/14.5)x(1/10)------(A)
Given that 2994/14.5 = 172.
So replace 2994/14.5 with 172 in (A)
172 x (1/10) = 17.2
Hope this will help you. Have a nice day.!

@Vikas.
Because its already mentioned in the question that 2994/14.5 = 172.
After calculations when we get this value. We substitute it to 172.

Can any one tell the rules of shifting of decimals during division and multiplication?
i.e. in case of division total decimals of both terms are added or subtracted?
