Answer 2

Step-by-step explanation:

Two cricket bats are sold Rs.700 each

For 1st bat:-

SP = Rs.700

Profit = 12%

→ CP = $\dfrac{100}{100+Profit\%} \times SP$

→ CP = $\dfrac{100}{100+12}\times 700$

→ CP = $\dfrac{70000}{112}$

→ CP of 1st bat = Rs.625

For 2nd bat:-

SP = Rs.700

Loss = 20%

→ CP = $\dfrac{100}{100 - Loss\%} \times SP$

→ CP = $\dfrac{100}{100 - 20}\times 700$

→ CP = $\dfrac{70000}{80}$

→ CP of 2nd bat = Rs.875

Total CP of two bats = 625 + 875 = Rs.1500

Total SP of two bats = 700 + 700 = Rs.1400

So:-

→ Profit = SP - CP

→ Profit = 1500 - 1400

→ Profit = Rs.100

Now:-

→ Profit % = $\dfrac{Profit}{CP} \times 100$

→ Profit% = $\dfrac{100}{1500} \times 100$

→ Profit% = $\dfrac{10000}{1500}$

→ Profit% = 6.66%

∴ Profit% of whole transaction = 6.66%
