Answer 1

Answer:

(B) 62.5%

Step-by-step explanation:

Let, 5 pens + 7 pencils + 4  erasers = x  rupees

so 10 pens  + 14 pencils + 8 erasers = 2*x rupees

also mentioned, 6 pens + 14 pencils + 8 erarsers = 1.5*x rupees

so (10-6) = 4 pens = (2-1.5)x rupees

so 4 pens = 0.5x rupees => 8 pens = x rupees

so 5 pens = 5x/8 rupees  = 5/8 of total (note x rupees is total amt paid by

amal) i.e 5/8 = 500/8% = 62.5% is the answer
