Maths chapter -4 Direct And Inverse Variation
Worksheet -1
1.(1) x= 6,8,12 And 21
y= 18,24,36 And 63
solution : x= 6,8,12 And C
y= 18,A,B And 63
It is given that x and y vary directly .
Therefore , 8by A =x 6 by 18
A x 6 = 18 x 18
A = 3/ x 8 by / 18 And 6 cut huya hai
= 24 ans
6 by 18 x= 12 by B
B x 6 = 18 x 12
B=3 / x 12 by / 18 and 6 cut huya hai 18 ko cut karke 3 aaya hai
B= 36 ans
and last
6 by 18 x= C by 63
c x 18 = 63x6
c= 21/ x 6 by 3/
63 and 18 cut huya hai 63 ko cut karke 21 aaya hai aur 18 ko cut karke 3 aaya hai
c= 21 ans
