Answer 1

Answer:

Combined value of 10Rs and 25Rs pen = 1550-350=1200 Rs

Let number of pens of 10 Rs = x

then x ⋅10+2x⋅25=1200

(x)60=1200

∴ x=20(number of 10 Rs pen)

∴ number of 20 Rs pen = 2 ⋅ 20=40 pens

and number of 50 Rs pen = 350/50=7 pens

Answer 2

Step-by-step explanation:

combined value of 10rs and 25rs pen = 1550 - 350 = 1200rs

let number of pens of 10rs = x

then x.

10+2x • 25 = 1200

( x ) 60 = 1200

therefore x = 20 ( number of 10rs pen )

therefore number of 20rs pen = 2•20 = 40 pens and number of 5rs pen = 350/50 = 7pens
