Question

Anu bought 3 note books and an instrument box for rupees 98.
price of the instrument box is 14 rupees more than that of the note book. What is the price of a note book and the instrumental box

​

Answer 1

Step-by-step explanation:

let price of one notebook be ' x'

Price of 3 notebooks= 3x

Price of instrument box = 14+x

Now, given that 3x + (14+x) = 98

or, 4x+ 14= 98

or, 4x=98-14=84

Therefore,x=84/4= 21

Price of notebook= Rs 21

Price of instrument box= 21+ 14=Rs35

Answer 2

Answer:

Let the cost of 1 notebook =x

Cost of 1 instrumental box =x+14

Cost of 3 notebooks =3x

Total cost=98

So,the equation = 3x +x+14 =98

:4x +14 =98

:4x=98-14 =84

:x=84/4 =21

Cost of instrumental box:x+14= 21+ 14 =35
