Answer 1

amount the shopkeeper is telling - 144 in a dozen

1 dozen - 12

for 12 notebooks 144

so , for 25 we will

multiply 25 x 12

= 25

x 12

= 300

therefore for 25 RS . 300

for 100 notebooks multiply 100 x 12

= 1200

therefore for 100 RS . 1200

for 40 notebooks multiply 40 x 12

= 480

therefore for 40 RS . 480
