A,B,C and D purchase a gift worth rupee 60. A pays 1/2 of what others are paying. B pays 1/3 of what other are paying and C pays 1/4 of what others paying. What is the amount paid by D?
Solution(By Apex Team)
A+B+C+D=60 ———– (1) Now According to Question, A= 1/2 (B+C+D) 2A = B+C+D Put the value of B+C+D in Equation (1) A+2A =60 3A=60 A=20 Now again according to Question B=1/3 (A+C+D) A+C+D= 3B By Putting the Value of A+C+D in Equation (1) we get, B+3B= 60 4B=60 B=15 Now again according to Question C= 1/4 (A+B+D) A+B+D = 4C By Putting the Value of A+B+D in equation (1) We get C+4C = 60 5C= 60 C=12 Since A+B+C+D= 60 20+15+12+D=60 D=60-47=13 Amount of D = Rs. 13
