Question

The cost of constructing a compound wall around a circular field at the rate of rupees 100 per m is rupees 1,76,000.find the cost of ploughing it at the rate of rupees 25 per sq m

Answer 1

HI !

Total amount of money = Rs 3000

Total no: of prizes = 63

No: of prizes worth Rs 100 = x 
No: of prizes worth Rs  25 = y

A.T.Q .,

x + y = 63      ----> (1)

100x + 25y = 3000     ----> (2)

Multiplying equation 1 by 25 , 

25x + 25y = 1575        ----> (3)

Solving equations 2 and 3 :-

25x + 25y = 1575
100x + 25y = 3000
-------------------------------
75x = 1425

x = 1425/75
   = 19

x + y = 63

y = 44

-----------------------------------------------------------------

No: of prizes worth Rs 100 = 19
No: of prizes worth Rs 25 = 44
