Total quanity of both ingredients in one packet of biscuits
= Quantity of flour + Quantity of sugar =212cups+123cups=(2×2)+12+(1×3)+23=4+12+3+23=52+53=5×3+2×56[∵LCMof2and3=6]=15+106=256 ∴ Total quantity of both ingredients used in 10 packets =10×Totalquantityofingredientsinonepacket =10×256=2506 = 4146
So , the estimated quantity for 2506 will lie between 41 and 42.
