If fees charged by the coaching centre was Rs 10000 for the first 3 years and Rs 12000 for the next three years then what is the total fees (in Rs. Crores) collected by the coaching centre in the last six years?

Total admissions in first 3 years = 100 + 150 + 150 = 400

=> Fees collected in the first 3 years = $$10,000 \times 400=Rs.$$ $$40,00,000$$

Total admissions in next 3 years = 250 + 350 + 300 = 900

=> Fees collected in the next 3 years = $$12,000 \times 900=Rs.$$ $$1,08,00,000$$

$$\therefore$$ Total fees collected by the coaching centre in the last six years = Rs. (40,00,000 + 1,08,00,000)

= Rs. 1,48,00,000 = Rs. 1.48 crores

=> Ans - (A)
