Test: Simplification- 1 - Question 20

Find the value of 22×(63÷7)÷6-{7×5+4-(3-5)÷2}

Detailed Solution for Test: Simplification- 1 - Question 20

Given:

Expression: 22 × (63 ÷ 7) ÷ 6 - { 7 × 5 + 4 - (3 - 5) ÷ 2 }

Formula Used:

Order of Operations (BODMAS/BIDMAS): Brackets, Orders (i.e., powers and square roots, etc.), Division and Multiplication, Addition and Subtraction

Calculation:

Simplify inside the brackets first:
22 × (63 ÷ 7) ÷ 6 - { 7 × 5 + 4 - (3 - 5) ÷ 2 }
= 22 × (63 ÷ 7) ÷ 6 - { 7 × 5 + 4 - (-2) ÷ 2 }
= 22 × (63 ÷ 7) ÷ 6 - { 35 + 4 + 1 }
= 22 × (63 ÷ 7) ÷ 6 - { 40 }

Now simplify the division and multiplication outside the brackets:
22 × 9 ÷ 6 - 40
= 198 ÷ 6 - 40
= 33 - 40

Finally, perform the subtraction:
= -7

The correct answer is option 1.
