Answer 1

Step-by-step explanation:

Given A man invests an amount of rs.20000 in the name of his 3 sons A,B and C in such a way that they get same interest after 3,4 and 5 years respectively at the rate of simple interest of 15%.find the share of B

• Given the interest is same after 3,4 and 5 years (that is different years) , so the ratio of share will be
•           Let the amount invested be p,q r respectively.
•            So we have
•                  p x 3 x 15 / 100 = q x 4 x 15 / 100 = r x 5 x 15 / 100 = A
•                   So we get  
•                    p = 20 / 9 A , q = 5/3 A, r = 4/3 A
•               So p: q : r = 20 / 9 A : 5/3 A : 4/3 A
•                   So we have
•                     p :  q : r = 20 : 15 : 12
•            So A : B : C = 20 : 15 : 12
•           Now we need to find the share of B. So we get
•        Share of B will be  
•                                   15 / 20 + 15 + 12  x 20,000
•                                    15 / 47 x 20,000
•                                      = Rs 6382.978
•                                   = Rs 6383
