Ali spends 30% monthly income on food articles, 40% of the remaining on conveyance and clothes and saves 50% of the remaining. If his monthly salary is Rs. 18400, how much money does he saves every month.?

Ali saves Rs 2576 every month

Step-by-step explanation:

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

Remaining amount = 18400 - 5520 = Rs 12880

Amount spent on conveyance and clothes = 40% of 12880

                              = 40/100 × 12880 = Rs 5152

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

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
