The costs of daily ticket of local train is Rs 130 and Monthly Pass costs Rs 3091.40. If I buy the Monthly Pass and travel for 29 days in a month than I save (in percentage)?
Train ticket cost for 1 day = Rs. 130
=> Cost for 29 days = 29 $$\times$$ 130 = Rs. 3770
Cost of monthly pass = Rs. 3091.40
=> Money saved = 3770 - 3091.40 = Rs 678.6
$$\therefore$$ Required % = $$\frac{678.6}{3770} \times 100 = 18\%$$
=> Ans - (B)
