34= 30

so , 60+30 = 90 Ans.

2. 43+78

43=40

78 = 80

so,40+80= 120 Ans.

3. 14 + 69

14 = 10

69 = 70

so , 10 + 70 = 80 Ans.

4. 86 + 19

86 = 90

19 = 20

so, 90+20=110 Ans.

5. 95 + 58

95=100

58 = 60

so, 100+60 = 160 Ans.

6. 77+63

77=80

63= 60

so, 80+60=140 Ans.

7. 356+275

356=400

275 = 300

so, 400+300=700 Ans.

8. 463+182

463=500

182=200

so, 500+200=700 Ans.

9. 538+276
