Solution
Cost of field A:
Rate of field A = Rs 95
Hence,
Cost = Area × Rate
= 756 × 95
= Rs 71820
756
× 95
3780
+ 68040
71820
Cost of field B:
Rate of field B = Rs 110
Cost = Area × Rate
= 432 × 110
= Rs 47520
432
× 110
000
43200
+ 43200
47520
Cost of field C:
Rate of field C = Rs 120
Cost = Area × Rate
= 513 × 120
= Rs 61,560
513
× 120
000
1026
+ 51300
61560
Now, cost of all three fields
= 71820 + 47520 + 61560
= Rs 1,80,900
