Cost price of adult ticket = Rs. 2200 and child ticket = Rs. 990 For 23 adults and 11 children, total cost = $$(23 imes 2200) + (11 imes 990)$$ = $$50,600 + 10,890$$ = Rs. $$61,490$$ If one child goes free with two adults, => 11 children will go with 22 adults, thus all the children will go for free. Cost of 23 adults = $$23 imes 2200 = Rs. 50,600$$ Discount % = $$frac{61490 - 50600}{61490} imes 100$$ = 17.71% => Ans - (A)
