There r 12 months in 1 year .Therefore using unitary method 12*7 = 84 months in 7 years Also 1/2 year means 6 months .Thus total of 84+6 = 90 months in 7& 1/2 years
(x/25)+6 =18 x =12*25
slope of the line will be same to that of the given line i.e. 3 Now let the eq. be y -3x = m (where m is any parameter) this line passes through (5,1) therfore satisfying it we get m = -14 thus, eq. of required line is y =3x -14
least number between the given range =36; to find the maximum no. divide 395 by 6 ;we get remainder to be 5 ;Therefore 395-5 will purely divided by 6 and also be the maximum no. in the given range Also total nos.:390=36+(n-1)6 calculate for n ; then apply
