(i) 27.5, 8.93, 0.759, 9.6   (ii) 0.83, 8.07, 17.9, 294.678 (iii) 0.53, 7.07, 77.7, 0.835   (iv) 9.38, 3.895, 109.5, 72.87, 0.005 (v) 9.008, 27.689, 247.96, 39.8   (vi) 325.7, 98.079, 0.87, 236.68

Solution- (i) 27.5+8.93+0.759+9.6 = 46.789
(ii) 0.83+8.07+17.9+294.678 = 321.478
(iii) 0.53+7.07+77.7+0.835 = 86.135
(iv) 9.38+3.895+109.5+72.87+0.005 = 195.65
(v) 9.008+27.689+247.96+39.8 = 324.457
(vi) 325.7+98.079+0.87+236.68 = 661.329

(iv) 64.375,

##### Que-4: What is to be added to 73.6 to get 91.03?

Solution- 91.03 – 73.6 = 17.43

##### Que-5: What is to be subtracted from 6.1 to get 0.785?

Solution- 6.1 – 0.785 = 5.315

##### Que-6: By how much should 32.987 be increased to get 60?

Solution- 60 – 32.987 = 27.013

##### Que-7: By how much should 72.5 be decreased to get 18.76?

Solution- 72.5 – 18.76 = 53.74

##### Que-8: The sum of two number is 34.02. If one of the number is 16.268, find the other.

Solution- sum of two number is 34.02
one number is = 16.268
other number be x
So, 16.268 + x = 34.02
x = 34.02 – 16.268
x = 17.752

##### Que-9: Sajjal bought a geometry box for Rs139.75 and an exercise box for Rs59.60 from a book shop. He gave a Rs500 note to the shopkeeper. What amount did he get back?

Solution- Total amount given to shopkeeper = Rs500
Cost of geometry box = Rs139.75
Cost of exercise box = Rs59.60
Amount to be paid = 139.75 + 59.60 = Rs199.35
Amount left = Rs500 – Rs199.35  = Rs300.65
