Simplification BODMAS Practice Problems: Level 02

Sol : Option B
Applying BODMAS rule: 5 ÷ √5 = 5/√5 = √5

Sol : Option C

= (1/8) + (3/7) - (1/8) + (3/7) = (6/7)

Sol : Option B
5(1/2) + 6(1/2) - 8(1/4) = (5+6-8) + ((1/2) + (1/2) - (1/4)) = 3(3/4)

Sol : Option C
22 – [9 – {6 – (10 –4-3 )}]
= 22 - [9 - {6 -) - (10 – 1)}] = 22 - [ 9 - { 6 - 9}]
= 22 - [9 - {-3}] = 22 - [9 + 3] = 22 - [12] = 22 - 12 = 10

Sol : Option A
10³ - 3³ - 2³/10²
= 1000-27-8/100
=965/100 = 9.65

Sol : Option D
(14)² – (.06)²
= 196 - .0036 = 195 .9964

Sol : Option A
37.5% of 800 - 6.25% of 1600
3/8 × 800 - 1/16 × 1600 = 300 – 100 = 200

Sol : Option A
(√289/34) × (68/√1156) × (√961/62)
= (17/34) × (68/34) × (31/62) = 1/2

Sol : Option C
6³ + 8³ -7³ / 6² + 8³ - 7²
=(216+512-343)/(36+64-49)
=(728-343)/(100-49)
=385/51

Sol : Option D
(19×9+31×10+32×11)/(233.25×2-50)
=171+310+350/466.5-50
=833/416.5
=2
