Hi I am a p6 student and may be able to help u, I also got a brother in P4
2u = $20CNS:
Pls help urgently. Thanks
Siti went shopping with some money. She spent $65 in shop A
and 3/5 of the remainder in Shop B.
She had $20 left.
Find the amount of money she had at first.
1u = $10
Hence she spent 3u = $30 at shop B
At first = 65 + 30 + 20 = 115
and a smart mum
My method:
2/5 of the remainder------$20
1/5 of the remainder------$10
5/5 of the remainder------$50
$50+$65= $106 -
If u need MD tell me

OK here was my explaination:
She had a sum of money you does know its amount.She spent $65 in shop A.
then, it spent 3/5 of its remaining also means 3/5 of $?-$65. She left $20. which is obviously 2/5 of the remaining.just find the total amount of remaining and add 65 dollar will do to find the answer. -
i guess she correct then, idoit brother calculation.

It's guess and check but my answer is 13:Dear Michell0328,
If you 1+2+3+...+14=91
So answer 14.
