__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)

Adding eq (3) and (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)

Adding equations (1) and (2)

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
