Rest she saves. Find: 21. how much is credited each month to her Provident Fund Account. uch is spent on food. () how much is paid as house rent. (ir) how much is spent on the education of children. (e) how much does she save every month. PERCENTAGE CHANGE (Decrease 9 = Decrease in value Original value 100 - Increase in value Original value ×100 % Remark: The change in value is always calculated on the original value. 120 Example 1. Solution: SOLVED EXAMPLES 80 K Increase 50 by 10% Increase 15% of 80- Increased value=(80-12)-92. Decrease 60 by 37% 100 35 Decrease-35% of 60- 60x -21 100 Decreased value-(60-21)-39. Find the number which when increased by 12% becomes 840 Let the required number be 1. Increase 12% of x= 12 3x 100 Increased number = 28x 28x -840 840 x 25 N 750. Hence, the required number in 750. Find the number which when decreased by 15% becomes 680. Let the required number bez. 3x Decrease = 15% of x = 20 15 100 3x 17x 20 20 Decreased number = 2 17x 20 =680⇒x= 680 x -800. 20 17 Hence, the required number is 800. By what number must a given number be multiplied to increase it by 20%! Let the given number be x. Increase in its value = 20% of x = 20 100 Increased value= 6 Hence, for an increase of 20%, the given number should be multiplied by A cycle costs 8500. Its cost is reduced to 3 7990. Find the decrease per cent in ita cost. Original cost of the cycle = 8500. Reduced cost of the cycle = 7990. Decrease in cost=? (8500-7990) = 510. 510 Decrease= 8500 x100 %-6%. 121 Example 2. Solution: Example 3. Solution: Example 4. Solution : Example 5. Solution: Example 6. Solution
