There are two errors in the bold part.
Firstly, the phrasal verb ‘stand by’ which means ‘adhere to or abide by (something promised, stated, or decided)’ has been written incorrectly. Therefore, ‘stood up’ must be replaced by ‘stood by’ in order to make the sentence correct.
Secondly, usage of plural case of possessive pronoun ‘their’ is also erroneous. Here the writer refers to the weather office which is a single institution. Therefore, ‘their’ should be replaced by ‘its’ to make it a grammatically correct sentence.

If a tank has 4x liters of total capacity and it holds 3x liters of water and if 30 liters of water is taken out, the tank becomes empty.
It means 3x liters of water is taken out
3x = 30 liters
x = 10 liters
Capacity of tank = 4x = 4 × 10 = 40 liters

Let B = 100
Then, A = 100 + 40% of 100 = 140
Let C = X
X - 20% of X = 100
0.8X = 100
X = 100/0.8 = 125
∴ A : C = 140/125 = 28 : 25

Total C.P. = Cost + Overhead Expenses
= Tk. (150 + 12% of 150)
= Tk. (150 + 18)
= Tk. 168
∴S.P.=Tk.(110/100 × 168) = Tk. 184.80

(10 men × 6 hours × 18 days)/1work = (15 men × 12 days × H hour/day)/1work
⇒ 6 hours/day

B's 10day's work = 1/15 × 10 = 2/3
Remaining work = (1−2)/3 = 1/3
Now, 1/18 work is done by A in 1 day
∴ 1/3 work is done by A in 18 × 1/3 = 6 days

We have:
(l - b) = 23 and 2(l + b) = 206 or (l + b) = 103
Solving the two equations,
we get: l = 63 and b = 40
∴ Area = (l x b) = (63 x 40) m² = 2520 m²

(2³)² = 4^x
(8)² = 4^x
64 = 4^x
(4)³ = 4^x
On comparing both sides x = 3
So,Value of 3^x = (3)³ = 27

Distance = Speed×Time
Distance = (6× 50)/60)km
Distance = 5 km
∴ Required time = Distance / Speed = 5/10 hrs = 1/2 hrs = 30 min

A:B:C = 35000 : 45000 : 55000 = 7 : 9 : 11
A's share = (7/27) × 40500 = Tk 10500
B's share = (9/27) × 40500 = Tk 13500
C's share = (11/27)× 40500 = Tk 16500

Treat 2:9 as 2/9 and x:18 as x/18,
So we get 2/9 = x/18
=> 9x = 36
=> x = 4

Let, Marked price = Tk. x
∴ x× 70/100 × 85/100 = 476
⇒ x = 476 × 100/70 ×100/85
⇒ x = Tk. 800 

Milk in the mixture
= (3/5 + 7/10 + 11/15)units
= 61/30 units.
Water in the mixture
=(2/5 + 3/10 + 4/15) units
= 29/30 units.
∴Required ratio
= 61/30 : 29/30
= 61:29
