Answer:
P= Rs 60000
A= Rs 79860
T=1 & 1/2 year = 3/2 years
     = 3/2 x 2 = 3 half years
R= ?  
Applying the formula A= P (1+r/100)^T
            79860  = 60000 (1+ r/100)^3
                   79860/60000 = (1+r/100)^3
                   1331/1000 = (1+r/100)^3
root(3)(1331/1000) = (1+r/100)
                      11/10 = 1+r/100
                      11/10 -1 = r/100
                       1/10 = r/100
                        r= 10 %

I’m assuming the numbers are 2/3 and 3/4 so find the common denominator. 2/3x4=8/12 and 3/4x3=9/12 so 8/12+9/12= 17/12 or 1 and 5/12
