A) 26850
B) 20900
C) 28875
D) 25850
Correct Answer :20900
Explanation :
Let, the CP of washing machine be x, and the CP of the chimney will be (57750  x)
SP of washing machine = SP of Chimney
x* (10024)/100 = (57750x)*(100+34)/100
x* 76/100 = (57750x)*134/100
76x = 134*57750  134*x
210x = 134*57750
x = 134*57750 / 210
x = 36850
CP of washing machine, x = 36850
CP of chimney = (57750  36850)
So, the cheaper item will be chimney = 20900
