Question
Two numbers are in the ratio 3: 2. If 6 and 5 are
subtracted from the first and the second number respectively, the ratio becomes 8: 5. The numbers are:Solution
Ratio of two numbers =3:2 Let the first number =3x and second =2x ATQ- (3x-6)/(2x-5) =8:5 15x-30=16x-40 16x-15x =40-30 X =10. First number =3x =3×10=30 Second number =2x =2×10=20

Solve the following expression and calculate the approximate value.
398% of 388 + 129% of 323.89 – 430.93
35.05% of 200.05 – 20.15% of 99.99 × 3.02 = ?
? 2 + (39.99 × 10.99 + 7.01) - (39.99 × 2.99 2 + 21.99) = 21.99 × 23.01
Direction: Solve the following expression and calculate the approximate value.
(5.78 + 3.12)² + 8.2² + 2 × 8.1 × (5.9 + 3.2)
...[(2/3 of 599.77) + (39.69% of 450.14)] ÷ [(5/8 of 399.79) - √120.91] = ?
