Question

Raj purchase 10 pens for rupees 150 and Manish by 7 pens for Rs 84 who got the pen cheaper solve the sum

Answer 1

Heya!


Raju buy 10 pens for ₹150

Raju buy 1 pens for = 150/10 = ₹15

manish buy 7 pens for ₹84


manish buy 1 pens for = 84/7 = ₹12

So, MANISH gotta cheaper pens!

Answer 2

$\huge{solution}$
first of all


the two statements are :

$1) \bold{raj \: purchase } \underline{10 } \bold{\: pens \: for \: 150 \: rupees}$
$2) \bold{manish \: purchase} \underline{7 \: pens} \bold{for \: 84 \: rupees}$
then


we have to find the cheapest value

so let's just divide to get one pen value


$150 \div 10 = 15 \to value \: of \: one \: pen \: that \: raj \: buy$
$84 \div 7 = 12 \to \: the \: value \: of \: one \: pen \: that \: manish \: buy$
no we got the value of one pen

so let's compare both

$15 \: and \: 12 \\ \huge{15} > \bold{12}$
but now we have to find cheaper value

so
$\red{cheaper \: means \: less \: according \: to \:me}$
then

$the \: lower \: number \: is \: 12 \to \: 12 \: is \: the \: answer$
so the final answer is :

$manish \: has \: cheaper \: value \: by \: 3 \: rupees as \: he \: have \: 12 \: than \: raj$
