Question

The value of [(-4) x (-9) x (-25)] &divide; [(-2) x (-3) x (-5)] is:a)30b)20c)10d)40Correct answer is option 'A'. Can you explain this answer?

Answer

Option (a) 30

Answer

LHS=[36×(-25)]
(-900)
RHS=[6×(-5)]
(-30)

(-900)÷(-30)
= 30

Answer

The value of [(-4) x (-9) x (-25)] is 900.

To get this answer, we simply multiply the three negative numbers together:

(-4) x (-9) x (-25) = 900

Remember that multiplying two negative numbers together gives a positive result, so when we multiply three negative numbers together, the result is positive.

Answer

Option (a) 30 because
LHS= -4×-9×-25= -900
RHS= -2×-3×-5= -30
-900÷-30= 30(- -=+)

Answer

Firstly we will solve brackets according to BODMAS rule,
(-4) x (-9) x (-25) = -900 (multiplication of odd number of negative integers gives a negative integer)
(-2) x (-3) x (-5) = -30 (-900) / (-30) = 30 (division of even number of integers gives a positive integer)

Answer

30

Answer

30 is the answer

Answer

Option a (30) is the correct answer

Answer

[(-4)x(-9)x(-25)]÷[(-2)x(-3)x(-5)]

=[36x(-25)]÷[6x(-5)] (On multiplying two negative integers we get a positive integer and on multiplying one negative and one positive integer we get negative integer)

=(-900) ÷ (-30) {On multiplying 36 with (-25) the product comes as (-900)}

= 30 (On dividing two negative integers we get a positive integer)

Answer= 30 (a)

Answer

According to BODMAS, first we will solve brackets.

First Bracket:

[-4 x -9 x -25] has 3 -ve signs which means answer would be negative.

(-4) x (-9) x (-25) = [(-4) x (-25)] x (-9) = 100 x (-9) = (-900)

Second Bracket:

[-2 x -3 x -5] has 3 -ve signs which means answer would be negative.

(-2) x (-3) x (-5) = [(-2) x (-5)] x (-3) = 10 x (-3) = (-30)

Simplifying:

[(-4) x (-9) x (-25)] � [(-2) x (-3) x (-5)]

= (-900)

�

(-30)

= 900

�

30 = 30
