weights of two friends ram and shyam are in the ratio 3: 5. if ram ' s weight is increased by 10 % and total weight of ram and shyam become 82.8 kg, with an increases of 15 %. by what percent did the weight of shyam has to be increased?
add(15, multiply(subtract(15, 10), divide(3, 5)))
"solution : given ratio of ram and shayam ' s weight = 3 : 5 hence , ( x - 15 ) / ( 15 - 10 ) = 3 / 5 or , x = 18 % . answer : option a"
