Arihant Expert Team Solutions for Exercise 1: Practice Exercise

If $\mathrm{A}$ for '$+$', $\mathrm{M}$ for '$\times$', $\mathrm{D}$ for '$÷$', $\mathrm{G}$ for '$>$', $\mathrm{L}$ for '$<$', then which of the following will be logically correct?

If $\mathrm{P}$ denotes '$\times$', $\mathrm{T}$ denotes '$-$', $\mathrm{M}$ denotes '$+$' and $\mathrm{B}$ denotes '$÷$', then $12 \mathrm{P} 6 \mathrm{M} 15 \mathrm{T} 16 \mathrm{B} 4$ is equal to:

If $\mathrm{P}$ denotes '$÷$', $\mathrm{Q}$ denotes '$\times$', $\mathrm{R}$ denotes '$+$', $S$ denotes '$-$', then $18 \mathrm{Q} 12 \mathrm{P} 4 \mathrm{R} 5 \mathrm{S} 6$ is equal to:

If $\mathrm{R}$ means '$÷$', $\mathrm{Q}$ means '$\times$', $\mathrm{P}$ means '$+$', then $18 \mathrm{R} 9 \mathrm{P} 2 \mathrm{Q} 8$ is equal to

If $\mathrm{L}$ stands for '$+$', $\mathrm{M}$ stands for '$-$', $\mathrm{N}$ stands for '$\times$', $\mathrm{P}$ stands for '$÷$', then $14 \mathrm{N} 10 \mathrm{L} 42 \mathrm{P} 2 \mathrm{M} 8$ is equal to

If $\mathrm{Q}$ means '$+$', $\mathrm{J}$ means '$\times$', $\mathrm{T}$ means '$-$' and $\mathrm{K}$ means '$÷$', then $30 \mathrm{K} 2 \mathrm{Q} 3 \mathrm{J} 6 \mathrm{T} 5$ is equal to

If $\mathrm{P}$ denotes '$÷$', $\mathrm{Q}$ denotes '$\times$', $\mathrm{R}$ denotes '$+$', $\mathrm{S}$ denotes '$-$', then $18 \mathrm{Q} 16 \mathrm{P} 4 \mathrm{R} 9 \mathrm{S} 6$ is equal to:
