Question

What will be units value of 191*191*252-211*566*114?

Answer 1

unit digit in 191*191*252 will be 2
as on multiplying last digits 1*1*2 we get 2
unit digit in 211*566*114 will be 4
on multiplying last digits 1*6*4 we get 24 whose last digit is also four
now since 4 is greater than 2 so we will let a one before two
thus 12 -4 = 8
units value for this will be 8

Answer 2

The units value of 191 × 191 × 252 - 211 × 566 × 114 is 8.

Step-by-step explanation:

The first number is 191 × 191 × 252.

• The digits in the units places of 191, 191 and 252 are 1, 1 and 2 respectively.
• When multiplied together, we get 1 × 1 × 2 = 2, so the units digit is 2.

The second number is 211 × 566 × 114.

• The digits in the units places of 211, 566 and 114 are 1, 6 and 4.
• When multiplied together, we get 1 × 6 × 4 = 24, so the units digit is 4.

Here, 2 > 4; thus we add 10 with 2 and then subtract 4 from it.

So, (10 + 2) - 4 = 12 - 4 = 8

Thus the digit in the units place of 191 × 191 × 252 - 211 × 566 × 114 is 8.
