Answer 1

Answer:

The greatest of the four numbers is: b) Y.

Step-by-step explanation:

If we substitute the greatest digit meaning 7 at the start of the number the number will be at least :

7000 [Meaning that other three digits are 0,0,0.So,if we substitute other digits in the place of three digits if will be larger.

But if we substitute 7 in the 2nd, 3rd or in the fourth place it wouldn't be the greatest.

As, X=*7** it can't be greatest.

Y=7*** it can be the greatest.

Z=**7* it can't be greatest.

T=***7 it can't be greatest .

Answer is :B) Y.✔✔✔
