1. Answer:

   A boy bought some pencils for $60. If he had paid $1 less for each pencil, he could have bought 5 more pencils. How many pencils did he pay for?

   Answer =15

   Now calculation starts as,

   As per the information given , if we decrease the cost per pencil by 1 then we can get more of 5 pencils, so

   Taking a simple approach

   We get a hint that it might be a number nearing 5, that is a cost for one pencil, so

   60/5=12

   And reducing amount per pencil by one,

   60/4=15

   Similarly ,

   60/3=20

   i.e, +5 than the previous number of pencils bought.

   And volla, we have the answer is 15.

2. Answer:

   Rs 5

   Step-by-step explanation:

   Cost of pencils = Total Cost / Cost of 1

   Cost of pencils = 60/x

   Cost of pencils with Rs 1 less = 60/(x-1)

   So, [60/(x-1)] – [60/x] = 3

   => 60x – 60x + 60 = 3x² – 3x

   => 3x² – 3x- 60=0

   => x² – x – 20 = 0

   => x² – 5x + 4x – 20 = 0

   => x(x – 5) + 4(x – 5) = 0

   => (x + 4)(x – 5) = 0

   x=5 as x cannot be negative . Thus Rs5 is the cost of each pencil and for Rs60 initially 60÷5 = 12 pencils could have been got.
