Add 10%: If the original number is 𝑋 X, then after adding 10%, it becomes: 𝑋 + 0.10 𝑋 = 1.1 𝑋 X+0.10X=1.1X Add another 10%: After adding another 10% to 1.1 𝑋 1.1X, it becomes: 1.1 𝑋 + 0.10 × 1.1 𝑋 = 1.1 𝑋 × 1.1 = 1.21 𝑋 1.1X+0.10×1.1X=1.1X×1.1=1.21X Subtract 5%: Finally, subtract 5% from 1.21 𝑋 1.21X, which becomes: 1.21 𝑋 − 0.05 × 1.21 𝑋 = 1.21 𝑋 × 0.95 = 1.1495 𝑋 1.21X−0.05×1.21X=1.21X×0.95=1.1495X So, the result is approximately 1.1495 times the original number.
