🙏🙂🙂🙂🙂
sir , with all respect in the last question as you have reversed the options and got option (d) correct... but sir in case if we do not reverse the options and calculate it as it is then 13/40= 0.325 and 16/45= 0.355 and the initial ratio 2/5= 0.4 and the increase value 1/3= 0.333 hence I am confused please help me sir please reply

No its not like that even free subscribers get the reply but it depends on person to person whether to reply or not...
Sir in the last qstn if we take the lcm of 2,3,5 ie 30 then distribute 30 in the given ratio we get A=6 B=9 C =15 then assume increase of A= x then C’s earning becomes 15+3X now this will always be a multiple of 3 so only option D satisfies.... is this method correct
Could you please explain me how do you write 1:3 as the ratio of a:c in the last ques?
