a. Rs 3200 | ||
b. Rs 12800 | ||
c. Rs 6400 | ||
d. Data inadequate | ||
Solution. Let the 6x, 19x and 7x be the money distributed among, P, Q and R respectively,
Hence, 6x + 19x + 7x = 32 x is the total amount of money
After R gives Rs 200 to Q, there ratio become 3x:10x:3x = 6x:20x:6x,
if we compare this ratio to the above ration we will see a change from 7x to 6x and 19x to 20x,
Hence there difference i.e x = 200,
Therefore the total amount of money = 32x = 32× 200 = 6400 Rs |
