Please solve the ticked answer​

Answer 1

Step-by-step explanation:

10 . Let the number be 'x'

therefore, 8x and 9x

ATP

8x + 9x = 153

17x = 153

x = 153/17

x = 9

therefore, 8 × 9 = 72

9 × 9 = 81 (Ans)

12 . Let the weight be 'x'

therefore, 6x , 9x and 5x

Total weight = 2 kg = 2000g

ATP

6x + 9x + 5x = 2000

20x = 2000

x = 2000/20

x = 100g

therefore, 6×100 =600g

9×100 =900g

5×100 =500g (Ans)
