Explanation

In this type of question, We need to find out the LCM of the given numbers.

LCM of 12, 15, 18 and 20;

12=2×2×3;15=3×5;18=2×3×3;20=2×2×5;

Hence, LCM = 2×2×3×5×3

Since, the soldiers are in the form of a solid square.

Hence, LCM must be a perfect square. To make the LCM a perfect square, We have to multiply it by 5,

hence,

The required number of soldiers

= 2×2×3×3×5×5

= 900

Explanation

6+27/3*9

=6+((27/3)*9)

=6+(9*9)

=6*81

=87

Explanation

Explanation

Let suppose Zain age is = x years

Nasir age is = 4x years

x + 4x = 60 years 

5x = 60 years 

x = 12 years 

Explanation

x a x b

x 3 x 4

Area = 12_2

Area 6 cm2

Explanation

60% of 20 = 60% x20

1200/100 = 12

Total games = 50

Played = 20

Remaining = 30

80% of 30 = 2400/100 = 24

= 12 +24 =36 games 

Explanation

Let suppose Arshad`s present age = × years

After 15 years = + 15 years 

5 years back = x - 5 years

x + 15 = 5x - 25

4x= 40

x = 10 years

Explanation

24% × 2 = x

48% = x

48 x 1/100 = x

48/100 = x

0.48 = x
