45. A tape manufacturer reduces the price of his heavy duty tape from Rs.30/- to Rs.28/- a reel and the price of a regular tape from Rs.24/- to Rs.23/- a reel. A computing center normally spends Rs.1440/- a month for tapes and 3/4 of this is for heavy duty tapes. How much will they save a month under the new prices?
Answer: 87
Explanation:Hd tape = (3/4)*1440 = 1080
Hd tape + Reg tape = 1440
(3/4)*1440 + Reg tape = 1440
SO, Reg tape = 360
HD tape = 1080
no. of reg tape = 360/24 = 15
no. of HD tape = 1080/30 = 36
For new price, Hd tape savings = (30-28) = 2
Reg tape savings = 24-23 = 1
Total savings = (36*2)+(15*1) = 87
