Such questions are the simplest as it needs you to just write the conditions accordingly which then simplifies and provides you the answer.

This question can be solved using two tricks which are shown below:-

Trick 1 :

1 – 1/4 = 3/4 (used for the 1st 7 days)

1/4 – 410 (used for 8th and 9th days)

(3/4)/7 ——- (1/4 – 10)/2

(3/4) x (2/7) = 3/14 ——- (1/4 – 10)

1/4 – 3/14 = (7 – 6)/28 = 1/28 ——- 10

28/28 ——- 10 x 28 =$ 280

Trick 2 :

7 days ——- 3/4

1 day ——- 3/28

2 days ——- 6/28

6/28 ——- (1/4 – 10) = 7/28 – 410

1/28 ——- 10

28/28 ——- 10 x 28 = $280

Thus Jeff received 280$ from his mother.

Let g be the number of grandchildren, and d be the number of dogs. They both have only one head, so the number of heads is

$g+d=33$

Grandchildren have 2 legs, while dogs have 4. So, the total number of legs is

$2g+4d=84$

From the first equation (the one for the heads) we can derive

$g=33-d$

Substitute this into the second to get

$2g+4d=84 \implies 2(33-d)+4d=84 \iff 2d=18 \iff d=9$

So, there are 9 dogs and (from the first equation

$g=33-9=24$

Answer:

It is stucked on the 9th floor

Step-by-step explanation:

We want to know the floor on which the elevator is stucked.

The main lobby is the ground floor and has a value of 0 floor

Ascends four floors with 6 people from the lobby

It is now on floor 4

Ascends another two so it is now on floor 4 + 2 = 6

Ascends another 2, then descend descends 3

That will be 6 + 2 -3 = 5th floor

Ascends 8 more , then descend 2

That will be 5 + 8 -2 = 11

Descends another 2, making 11 - 2 = 9

It is stucked on floor 9

Kindly note, when it ascends, that is a positive value, when it descends, that is a negative
