## Answers to Maths IQ Questions

A1.
Let us use the following symbols:
Clock...........L
Snowman.......S
Calendar.......C
L-S= 18...(1)
C- S = 6......(2)
C+ L= 28.....(3)
Subtracting eq (1) from (2)
C-L = -12......(4)
2C= 16
C= 8, From eq (2) S=2
from (1), L=20
C+L+S= 30.

A2.
Let us use the following symbols:
S..........Star
N..........Snowman
P......... Penguin
S+N = 15...(1)
N+P=20....(2)
S-N=5....(3)
2S = 20, S= 10
substituting the value of S in (1).
N=5
Substituting the value of N in (2)
P=15
Therefore S+N+P = 30

A3.
Let us use the following symbols:
C.........Cap
L.........Clock
N ........New year
Given:
CL+LN+NC=26..........(1)
CL+LN =18................(2)
C + N = 6.................(3)
Substituting value from (2) in (1).
NC= 8............(4)
From equation (3)
N= 6-C,
Substituting the value of N in (4)
(6 -C)x C=8,
C² - 6C+ 8 = 0
C²-4C-2C +8=0
C(C-4)-2(C-4)=0
C=2, C=4
If C=2, N=4 and if C=4, N=2 and
from eq (2)
CL+LN =18., 2L+4L=18, L= 3
CxLxN= 2x3x4 = 24.

A4.
14
Let me use the following notations for the figures
C........circle
P..........pentagon
T..........Triangle
Given
C+C+C=12..... 3C = 12.......(1)
C+P =19........ 4+P = 19....(2)
T-P = 10......... T- P = 10....(3)
From (1)... C = 4,
From (2).....P = 15
From (3)....T = 25
Therefore
C+T-P = 14

A5.
150
Let me use the following notations for the figures
S........star
C........circle
F.........flower
Given:
S x S x S = 27, S= 3...............(1)
S x S+ C= 14, 3x3 +C= 14....(2)
C x C +F= 35, ........................(3)
From (1), S=3
From (2), C=5
From (3) F=35-25= 10
Therefore, SxFxC= 3x10x 5= 150
