Ali saves Rs 2576 every month

Step-by-step explanation:

  • Step 1: Given Ali's monthly salary = Rs 18400. Calculate the amount spent on food articles

Amount spent on food = 30% of 18400 = 30/100 × 18400 = Rs 5520

  • Step 2: Find the remaining amount.

Remaining amount = 18400 - 5520 = Rs 12880

  • Step 3: Find amount spend on conveyance and clothes

Amount spent on conveyance and clothes = 40% of 12880

                              = 40/100 × 12880 = Rs 5152

  • Step 4: Find his monthly savings.

Monthly savings = 50% of 5152 = 50/100 × 5152 = Rs 2576
