- 600/24=25, max 25 rs/tea
24*25=600
24*24+24=600 => minm 24.1 rs/tea(let)
1000/15=66.66 , max 66.66 rs/coffee
65*15+25=1000
64*15+40=1000
63*15+55=1000
62*15+70=1000
62.5*15+62.5=1000 => minm 62.6 rs/coffee

- 10 years agoHelpfull: Yes(1) No(0)
- 30 is the correct ans..........
as initially 1 teacup cost=600/24 =25
1 coffecup cost= 1000/15 =200/3
hence,8 teacup cost= 8*25=200
remaning money left= 2200-200= 2000
max no of cup of cofee= 2000*3/200= 30cups
- 10 years agoHelpfull: Yes(1) No(1)

- 10 years agoHelpfull: Yes(0) No(22)
- For rs 600 if he can buy max 24 tea cups then each price is Rs 25
For rs 1000 if he can buy max of 15 cups then each price is Rs 66
2200 = 8 * 25 + 30 * 66 and remaining amount is 20 rupees

As given,
L+A=12 .....(1)
L+T=4 .......(2)
A=8+L
or L-A=-8 ......(3)
A=8+T .......(4)
Simply adding eq. 1 and 3
We get..
2L=4
So, L=2
