Question

If \(\left\{ \begin{matrix} ''⊕\;''~means~''-\;'', \\ ''⊗\;''~means~''\div\;'', \\ ''\text{ }\!\!\;Δ\;\!\!\text{ }''~means~''+\;'', \\ ''\;∇\;''~means~''\times\;'', \\ \end{matrix} \right.\)

then, the value of the expression Δ 2 ⊕ 3 Δ ((4 ⊗ 2) ∇ 4) =

1. -1
2. -0.5
3. 7
4. 6

Answer 1

Correct Answer - Option 3 : 7

Concept:

Replace the symbol as per their standard sign and solve using BODMAS.

Calculation:

Given:

Δ 2 ⊕ 3 Δ ((4 ⊗ 2) ∇ 4) = + 2 - 3 + ((4 ÷ 2) × 4)

∴ + 2 - 3 + (2 × 4)

∴ + 2 - 3 + 8

∴ 10 - 3 = 7
