Number of persons = 28

Each person gets = RS. 62.45

Total amount distributed to 28 persons = Rs. 62.45 x 28 = Rs. 1748.60

Amount left undistributed = Rs. 5.78

Total amount = Rs. 1748.60 + 5.78 = Rs. 1754.38

The required number can be formed by subtracting 27.78 from 83.407

Required number = 83.407 – 27.78 = 83.407 – 27.780 = 55.627

Cost of 1 kg fruit = Rs. 27.50

(ii) 7.84 + 0.3 – 4.016

= 7.840 + 0.300 – 4.016

= 8.140 – 4.016

= 4.124

(iii) 2.987 – 1.25 – 0.54

= 2.987 – 1.79

= 2.987 – 1.790

= 1.197

(iv) 52.9 – 231.666 + 204

= 52.9 – 231.666 + 204.0

= 256.9 – 231.6

= 256.900 – 231.666

= 25.234
