Correct Answer:

90

Explanation:

                           50 P.         25 P.          10 P.          

No. of Coins   ⇒      7      :      4        :     3        

           Value  ⇒      3.5      :   1       :      .3         ⇒   4.8R

 

4.8R = 144 (given)

     1R = 30

No. of 10 P. coins = 3R = 3 × 30 = 90
