Pl help me solve this.... :faint:

hi offering my help..

always remember the hard rule, use bigger area minus smaller area to find shaded area.

80 x 57.8 = 4624m2 (smaller area, field)
80 + 1.1 + 1.1 = 82.2m (length of bigger area, field and path)
57.8 + 1.1 + 1.1 = 60m (breadth of bigger area, field and path)
82.2 x 60 = 4932m2 (bigger area)
4932 - 4624 = 308m2 (area of path)

Ans = 308m2

Hi, pls help me to solve this question.

Tank A and Tank B each contain some fish. If John transferred 12 fish from Tank A to Tank B, both tanks will have the same number of fish. If he transferred 4 fish from Tank B to Tank A instead, Tank A will have 5 times as many fish as Tank B. How many fish are there in each tank?

TIA

4U = 28

U = 7.

Initial no of fishes in A is 11 and B is 35.

[Jamesbond]

CNS:

4U = 28

U = 7.

Initial no of fishes in A is 11 and B is 35.

Hi CNS, Sorry to interrupt....Shud it be the other way round...
Tank A-35 and Tank B-11.

Hi htn,

If you draw the model,

you will get that 4 units = 32
in other word, 1 unit = 8
So,
A = 8 + 4 + 12 + 12 = 36
B = 8 + 4 = 12

Cheers

From a p4

For a, find the relationship between figure no. and the no. Of blocks used. (x5-1) then, so, 6x5-1=29 Ans : 29
For b, Find the relationship. (x2+1) so... 31-1 divide by2=15
Ans:15From gold




:thankyou:
