Answer:
11.78
Step-by-step explanation:
buying price is always 100%
N pays 14.58
if 12.5 = 14.58
∴100 will be 12.96 forming the buying price of M from L
IF 110 = 12.96
∴100 =11.78 S.P of K to L
= 11.78

Answer:
11.78
Step-by-step explanation:
K' sp = L's CP
N's cp = M's Sp
N's Cp(M's Sp) = 14.58
SP= (100+gain %)*CP/ 100
14.58 = (100+12.5/100)* CP
M's CP( L's SP) = 12.96
(L's)CP = (100/100+10)*12.96
= 11.781....
since K's sp is l's cp = 11.78
