Maruti surges; weaker yen seen boosting margins

MUMBAI (Reuters) - Maruti Suzuki Ltd ended up 7.3 percent after rising as much as 8.6 percent on Friday, on hopes a weaker yen currency would improve margins by reducing the costs of importing auto parts from Japan after the Bank of Japan unleashed unprecedented monetary expansion.

The yen slid to a 3-1/2 year low against the dollar on Friday, after suffering its biggest one-day tumble since late 2008 on Thursday, on the back of the BOJ's radical campaign to attack deflation.
