Dipesh bought 3 notebooks and 2 pens for Rs. 80. His friend Ramesh said that price of each notebook could be Rs. 25. Then three notebooks would cost Rs.75, the two pens would cost Rs. 5 and each pen could be for Rs. 2.50. Another friend Amar felt that Rs. 2.50 for one pen was too little. It should be at least Rs. 16. Then the price of each notebook would also be Rs.16. Lokesh also bought the same types of notebooks and pens as Dipesh. He paid 110 for 4 notebooks and 3 pens Whether the estimation of Ramesh and Amar is applicable for Lokesh? |

Answer» Ramesh’s ESTIMATION is WRONG but Amar’s estimation is correct. If the PRICE of one notebook is Rs. 25 and the price of one pen is Rs. 2.50 then, The cost of 4 notebooks WOULD be : `4 xx 25 = 100` Rs And the cost for 3 pens would be : `3 xx 2.5 = 7.5` Rs Lokesh should have paid `100 + 7.5 = 107.5` Rs. But he paid Rs. 110, thus Ramesh’s estimation is wrong. Now, consider the prices mentioned by Amar. The cost of 4 notebooks, if one is for Rs.16, would be : `4 xx 16 = 64` Rs And the cost for 3 pens, if one is for Rs. 16, would be : `3 xx 16 = 64` Rs Lokesh should have paid `64 + 48 = 112` Rs but this is more than the price he paid. Therefore, Amar’s estimation is also wrong. Thus (d) is correct option. |
