Answer:
Step-by-step explanation:
Total price of 5 pens and 7 pencils by seller One = 551/3 + 142/3
= (551+142)/3
= 693/3 = Rs. 231
Total price of 7 pens and 5 pencils by seller Second = 782/5 + 103/4
(LCM of 4& 5 = 20 )
= (4*782 + 5*103)/20
= (3128 + 515)/20
= 3643/20 = Rs. 182.15
So we should by from seller second.
