In a certain supermarket, a triangular display of cans is arranged in 10 rows, numbered 1 through 10 from top to bottom. Each successively numbered row contains 3 more cans than the row immediately above it. If there are fewer than 150 cans in the entire display, how many cans are in the fifth row? | [
"14",
"10",
"11",
"13"
] | D | Let x be the number of cans in row 1.
The total number of cans is x + (x+3) + ... + (x+27) =
10x + 3(1+2+...+9) =
10x + 3(9)(10)/2 =
10x + 135
Since the total is less than 150, x must equal 1.
The number of cans in the 5th row is 1 + 3(4) = 13
The answer is C. | AquaRat_train |

9 children can complete a piece of work in 360 days; 18 men can complete the same piece of work in 72 days and 12 women can complete it in 162 days. In how many days can 4 men, 12 women and 10 children together complete the piece of work? | [
"81 days",
"124 days",
"126 days",
"68 days"
] | A | Explanation:
1 child’s 1 day’s work = 1/360 ×9 = 1/3240
10 children’s 1 day’s work = 1/324
1 man’s 1 day’s work = 1/72 × 18 = 1/1296
4 men’s 1 day’s work = 1 ×4/1296 = 1/324
12 women’s 1 day’s work = 1/162 given
Then, (4 men + 12 women + 10 children)’s 1 day’s work = 1/324 + 1/162 + 1/324
