1. Let the unknown number be x.
So According to question,
(2a + 8b + 10) - x = -3a + 7b + 16
» -x = (-3a + 7b + 16) - (2a + 8b + 10)
» -x = -3a + 7b + 16 - 2a - 8b - 10
» -x = -5a - b + 6
» x = 5a + b - 6
2. Circumference of the circle = 154 cm
» 2πr = 154
» r = 154 × 7/22 × 1/2
» r = 24.5 cm (Radius)
Area of the circle = πr²
= 22/7 (24.5)²
= 22/7 (600.25)
= 1886.5 sq. cm
3. 3,18,65,00,000 = 3.1865 × 10⁹

4. Length of the rectangle = 35 cm
Perimeter of the rectangle = 100 cm
» 2(l + b) = 100
» 2(35 + b) = 100
» 70 + 2b = 100
» 2b = 30
» b = 15 cm (Breadth)
∴ Area = Length × Breadth
= 35 cm × 15 cm
= 525 sq. cm
