The value of Set 4 is 43
Quick tip : Observation helps!
Given data :
Set 1 : A pair of shoes + A pair of shoes + A pair of shoes = 30
Set 2 : A simple boy + A simple boy + A pairs of shoes = 20
Set 3 : Pair of packets + Pair of packets + A simple boy = 13
To find :
Set 4 : Single shoe + (A simple boy + A pair of packets + A pair of shoes) x Single packet = ?
Solution :
Here, firstly, we need to find the values of
Single shoe
A simple boy
A pair of packets
A pair of shoes
Single packet
From set 1,
3 pairs of shoes = 30
So, The value of a pair of shoes = 30/3 = 10
A pair contains 2 shoes.
If 2 shoes = 10, 1 shoe = 10/2 = 5
Therefore, The value of a pair of shoes = 10 and the value of 1 shoe = 5
From set 2,
2 sets of a simple boy + a pair of shoes = 20
On substituting the value of a pair of shoes in it, we get :
2 sets of simple boy + 10 = 20
2 sets of a simple boy = 20 - 10
2 sets of a simple boy = 10
From this, one simple boy = 10/2 = 5
Therefore, The value of a simple boy = 5
From set 3,
2 pairs of packets + a simple boy =13
On substituting the value of a simple boy in it, we get :
The value of 2 pairs of packets + 5 = 13
The value of 2 pairs of packets = 13 - 5
The value of 2 pairs of packets = 8
If the value of 2 pairs of packets is 8, the value of a pair of packets = 8/2 = 4
A pair contain 2 packets whose value is 4. Value of one packet = 4/2 = 2
Therefore, the value of pair of packets = 4 and the value of 1 packet = 2
Coming to Set 4, We find :
- 1 shoe
- A set of ( A simple man, A pair of shoes, A pair of packets)
- 1 packet
- The value of set 4
= Single shoe + (A simple boy + A pair of packets + A pair of shoes) x Single packet
On substituting the values, we get
= 5 + ( 5 + 4 + 10 ) x 2
By BODMAS rule, the order of solving is set, multiplication, sum
= 5 + ( 19 ) x 2
= 5 + 38
= 43
Therefore, the value of Set 4 is 43
