**Que-1: Add :**

**(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

**Que-2: Find the difference :**

**(i) 17.05 – 9.78 (ii) 30.23 – 17.495 (iii) 107.5 – 58.69 (iv) 60 – 18.35 ****(v) 48.3 – 29.571 (vi) 100 – 72.745 (vii) 215.4 – 69.845 (viii) 1.5 – 0.703 ****(ix) 42 – 0.764**

**Solution- **(i) 7.27, (ii) 12.735 (iii) 48.81 (iv) 41.65 (v) 18.729 (vi) 27.255 (vii) 145.555 (viii) 0.797 (ix) 41.236

**Que-3: Simplify :**

**(i) 74.8+68.79-47.609-7.08 (ii) 68.3-102.735+217.96-37.7 ****(iii) 203.5-43.76-9.89-13.086 (iv) 77.7-7.555-5.77**

**Solution- **(i) 88.901,

(ii) 145.825,

(iii) 136.764,

(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
