Question
If β+β means βΓβ, βββ means βΓ·β,
βΓβ means β+β, and βΓ·β means βββ, then what will come in place of the question mark (?) in the following equation? 72 Γ 6 + 12 β 4 Γ· 8 = ?Solution
Given conditions: β+β means βΓβ βββ means βΓ·β βΓβ means β+β βΓ·β means βββ Transforming the expression: Given equation: 72 Γ 6 + 12 β 4 Γ· 8 = ? After replacing the symbols based on the given conditions: = 72 + 6 Γ 12 Γ· 4 β 8 = 72 + 72 Γ· 4 β 8 = 72 + 18 β 8 = 90 β 8 = 82 Hence, option 2 is the correct answer.
5/2 of 5/6 of 12/5 of 54 % of 5250 = ?

52% of 400 + √(?) = 60% of 600 - 25% of 400
18(1/3) + 9(2/3) β 10(1/3) = 1(2/3) + ?
24 × ?2 – 11 × 4 = 1900
- Calculate the value of this expression:
(180 - 90 Γ· 6 of 2) Γ· 5 + 3 of 16 Γ· 4 - 12 of 4 Γ· 8 (72 × 52 + 1555 )/(79+60) = 2000 ÷ ?
- Determine the value of βxβ if (7 Γ 256 β 525 Γ· 21) Γ· 28 = β2500 β x.
- What will come in place of the question mark (?) in the following questions?
180Γ·3Γ2+6=? (? Γ 3)2 - 85 = 115 Γ 5 + 69
