Benny,connie and daniel had $8600 altogether. benny spent 4/7 of his money, Connie spent $380, Daniel spent half the amount of what Benny has spent. If they have same amount of money left, how much more money did benny have than connie at first?

Benny's money --> 7 units, Benny's money left --> 3 units
Connie's money --> 3 units + $ 380
Daniel's money --> 3 units + 2 units (Benny spent 4 units) = 5 units

Amount of money Benny had more than Connie --> 4 units - $380

Total --> 15 units + $380
15 units + $380 = $ 8600
1 unit --> $548

4 x $548 - $380 = $1812 -- Benny had $ 1812 more than Connie at first.

cheers.

Thank you....

Mr Tan bought 5 kg of flour. He used 3/4 kg of it to bake some muffins and 7/8 kg of it to bake a cake. How much flour was left.

I think there must have been a typo error. 3/4 + 7/8 = more than 1. Probably the question reads and 7/8 of the remainder to bake a cake.

ya may be..

i spent 1/9 of my salary on a television set and 5/8 of the remainder on a refrigerator. I saved the remaining $420. How much i did spend on the refrigerator?

Hi
spent 1/9 salary --> left 8/9 salary (remainder)
spent 5/8 of remainder on refrigerator
= 5/8 x 8/9 salary = 5/9 salary
left --> 8/9 - 5/9 = 3/9 salary
3/9 salary --> $420
5/9 salary --> $700
$700 spent on refrigerator

cheers.

Thank you. Understood.
