Sheela will return Rs. 11,400 including the interest of Rs. 1400 at the end of 2 years.Step-by-step explanation:Sheela borrowed = Rs. 10,000Rate = 7%Interest at the end of = 2 yearsAmount and interest =Using the formula:

Principal = Rs. 10,000Rate = 7%Time = 2 years

Interest=Rs1400_______________

Principal = Rs. 10,000Simple Interest = Rs. 1,400

Therefore, 

Shela will return Rs. 11,400 including the interest of Rs. 1400 at the end of 2 years.

Intersecting secant-tangent theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12
