Question

if there are 6 students in the class and each is having x pencils then what is the value of x

Answer 1

Answer:

(i)

Total of 10 students took part in the quiz,

number of girls + number of boys =10

x+y=10.....(1)

number of girls is 4 more than boys,

number of girls = 4+ number of boys

x=y+4

x−y=4......(2)

solving (1) and (2), we get,

x=7

y=3

Number of girls =7

Number of boys =3

(ii)

Let the cost of one pencil be x

let the cost of one pen be y

5x+7y=50.......(1)

7x+5y=46.........(2)

solving (1) and (2), we get,

x=3

y=5

cost of pencil =3

cost of pen =5

(iii)

Number of skirts purchased = 2 * number of pants purchased -2

⇒y=2x−2

2x−y=2........(1)

Number of skirts purchased = 4 * number of pants purchased -4

⇒y=4x−4

4x−y=4........(2)

solving (1) and (2), we get,

x=1

y=0

Number of pants purchased =1

Number of skirts purchased =0

solution
