Question

sum of two numbers is 74 one number is 10 more than the other what are the numbers ??

\huge{ \red{ \fbox{↪ answer : }}}

↪ answer :

Let us say the other Number is x.

One of the Number is = 10+x

sum of the two Number = 74

10+x+x=74

2x=74−10=64

x = 32

& another No is 32 + 10 = 42.

Question

the perimeter of a rectangle is 13 cm and its breath is 2 3/4 cm find its length

\huge{ \red{ \fbox{↪ answer : }}}

↪ answer :

given -

breath \: - 2 \times \frac{3}{4}breath−2×

4

3

= \frac{2 \times 4 + 3}{4} = \frac{11}{4}=

4

2×4+3

=

4

11

let the length of rectangle be X

now - perimeter = 2 × length × breath

perimeter = 2 ( X + 11/4 )

putting perimeter of rectangle - 13cm

= 13 = 12 ( X + 11/4 )

\frac{13}{2} = x + \frac{11}{4}

2

13

=x+

4

11

x \: + \frac{11}{4} = \frac{13}{2}x+

4

11

=

2

13

x \: = \frac{13}{2} - \frac{11}{4}x=

13

−

11

x \: = \frac{13 \times 2 - 11}{4}x=

4

13×2−11

x \: = \frac{26 - 11}{4}x=

4

26−11

x \: = \frac{15}{4}x=

4

15

x \: = 3\ \frac{3}{4}x=3

3

therefore length of the rectangle = 3 3/4
