Question
The average value of the property of Arjun, Bhavna and
Deepak is Rs. 78 lacs. The value of the property of Arjun is Rs. 20 lacs less than the value of Bhavna, and Rs. 10 lacs less than the value of Deepak. Find the value of the property of Deepak.Solution
Total value of the property of Arjun, Bhavna and Deepak = 78 × 3 = Rs. 234 lacs
Let the value of the property of Bhavna = Rs. x lacs
The value of the property of Arjun = Rs. (x – 20) lacs
The value of the property of Deepak = Rs. (x – 20 + 10) lacs
x + x – 20 + x – 10 = 234
3x – 30 = 234
3x = 234 + 30
3x = 264
x = Rs. 88 lacs
The value of the property of Deepak = 88 – 10 = Rs. 78 lacs
