Question

1 The value of x in the equation 1/3x + 1/4x + 1/2x + 1/6x = 5 is :​

Answer 1

Answer:

512.50 (D)

Step-by-step explanation:

☆Given:

The difference between compound intrest and

Simple intrest is 12.5

☆To find

Principle and compound intrest

☆Solution:

▪P = ?

▪I = 5%

▪N = 2

P[(1+i)^n-1]P[(1+i)n−1] - p × i × t = 12.5

P[(1+0.05)^2-1]P[(1+0.05)2−1] - p × (⁵/₁₀₀) × 2 = 12.5

[(1.05)^2-1] = 0.1025[(1.05)2−1]=0.1025

0.1025p - \frac{10p}{100}10010p = 12.5

\frac{10.25p-10p}{100}10010.25p−10p = 12.5

0.25p = 1250

P= 1250 ÷ .25 = 5,000

CI = P[(1+i)^n-1]CI=P[(1+i)n−1]

CI = 5000 [(1.05)^2-1]

CI = 5000 × 0.1025

CI = 512.50
