Question

one third of Rahul saving in national saving certificate is equal to one half of his savings in public provident fund if he has rupees 150000 as total savings how much has He saved in public provident fund

Answer 1

Let, savings in the national saving certificate = x
       savings in the public provident fund = y
As given, one third of Rahul saving in national saving certificate is equal to one half of his savings in public provident fund.
                                   x/3 = y/2
                                    2x = 3y
 x in terms of y             x = 3y/2
Assuming total savings are only from national saving certificate and public provident fund,
                               x + y = 1,50,000
                             3y/2 + y = 1,50,000
                               5y/2 = 1,50,000
                                5y = 3,00,000
                                  y = 60,000
 ∴The amount he saved in public provident fund = 60,000

Hope my answer helps you..

Answer 2

Answer:

60,,000

Step-by-step explanation:

let savings in national savings certificate and public provident fund be Rs.x and Rs(150000-x)

1/3x=1/2(150000-x)

x/3+x/2=75000

5x/6=75000

x=75000×6/5

x=15000×6

x=90000

Therefore,savings in public provident fund =150000-90000

=60000/-
