Say John's earning last month was $100. John spent 40 percent of his earning last month on rent -->$40 on rent;
30 percent less than what he spent on rent to purchase a new dishwasher --> $40*0.7=$28 on the dishwasher.

Left over amount 100 - (40 + 28) = $32. Answer: B. Hope it's clear. _________________ Intern Joined: 07 Mar 2013 Posts: 6 Followers: 0 Kudos [?]: 2 [0], given: 0 Re: John spent 40% of his earning last month on rent and 30% [#permalink] ### Show Tags 14 Mar 2013, 04:15 Bunuel wrote: musical33 wrote: John spent 40 percent of his earning last month on rent and 30 percent less than what he spent on rent to purchase a new dishwasher.

what is the .7 ?

30 percent less than what he spent on rent to purchase a new dishwasher = 40 - 0.3*40 = 0.7*40.

Or: 30 percent less than what he spent on rent to purchase a new dishwasher means that he spent 70% of the rent on the dishwasher.

Hope it's clear.
