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 centre
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 Posted / trisha sah
Total Expenditure on tapes=Rs.1440
Total Expenditure on heavy duty tapes=3/4*1440=Rs.1080
Total reels of heavy duty tape=1080/30=36
Total savings on heavy duty tape=36*(30-28)=Rs.72
Total Expenditure on regular tapes=1/4*1440=Rs.360
Total reels of regular tape=360/24=15
Total savings on regular tape=15*(24-23)=Rs.15
Total Savings=Rs.72+Rs.15=Rs.87

Alok and Bhanu play the following min-max game. Given the expression N = X - Y – Z where X, Y and Z are variables representing single digits (0 to 9), Alok would like to maximize N while Bhanu would like to minimize it. Towards this end, Alok chooses a single digit number and Bhanu substitutes this for a variable of her choice (X, Y or Z). Alok then chooses the next value and Bhanu, the variable to substitute the value. Finally Alok proposes the value for the remaining variable. Assuming both play to their optimal strategies, the value of N at the end of the game would be • 4 • -18 • 9 • 2
