Jennifer had $30 to spend on herself. She spent 1/5 of the money on a sandwich, 1/6 for a ticket
to a museum, and 1/2 of it on a book. How much money does Jennifer have left over? | [
"$5",
"$14",
"$15",

"24",
"16",
"20",
"15"
] | D | 32,000 = 8,000(1 + x)^10
4 = (1+x)^10 = 2^2
(1+x)^10 = ((1+x)^5)^2 = 2^2
Therefore, (1+x)^5 = 2
64,000 = 8,000(1 + x)^n
(1+x)^n = 8
(1+x)^n = 2^3
(1+x)^n = ((1+x)^5)^3 = (1+x)^15
Therefore, n = 15.

"24",
"14",

] | D | Explanation:
Let cost price of lemons be x.
Selling price of lemons becomes CP - loss.
=>SP=x-(20/100)x
=>40=x(80/100)
=>50
So 45 lemons cost Rs 50
Cost of 1 lemon = 50/45 Rs
Cost of 24 lemons = (50/45)*24 =80/3 Rs
Selling Price of 24 lemons =(80/3)+(20/100)(80/3)=Rs 32

2, 7, 10, 22, 18, 37, 26 | [
"22",
"52",

] | B | Explanation:
This question contains two series’ running simultaneously:
=> The numbers in odd places are increasing by 8
2 + 8 = 10
10 + 8 = 18
18 + 8 = 26
=> The numbers in even places are increasing by 15
7 + 15 = 22
22 + 15 = 37
37 + 15 = 52
Therefore, Next number will be 37+15= 52
