For first image, 4+8=12-3 =9

For second image, 2+6 = 8 - 5 = 3

For third image, 10+2= 12 - 1 = 11

প্রথম শত্রুমুক্ত হয় যশোর জেলা ১৯৭১ সালের ৭ ই ডিসেম্বর। যশোরের শার্শা উপজেলাকে স্বাধীনতা যুদ্ধের প্রবেশদ্বার বলা হয়। 

option 1: for x = 6 & y = -2, x+ 4y becomes -2 which is not greater than 1.

option 2: for x = 6 & y = -2; -4y = 8 which is not true for x>-4y

option 3: for x = 6; -4x = -24 & y can be -25 so it's not also true

50% of x equals the sum of y and 20. Expressing this as an equation yields: ( 50/ 100 ) × x = y + 20 x/ 2 = y + 20 x = 2 y + 40 x – 2 y = 40

since he talks a break after each installment,(until reaching the 50 mile point ;one after 10 miles ;  one after 20 miles ; final one after 40 miles .The 50 th mile is his destination.)he takes 4 breaks ,and since each break  lasts 6min The net time spent in the breaks is=4*6 min=24 mins  

As the man walks 50 miles in 5 installments of 10 miles each, each installment should take him 1hr. hence,the total time for which he walked equals  5*1hr =5hr=5*60=300min. Hence,the total taken to reach the destination is =300+24=324mins

(x-2)2 

= x2- 4x + 4

= x2- 4x +3 + 1

= 0 + 1

= 1

Speed of the train relative to man = (63 - 3) km/hr

                = 60 km/hr = 50/3 m/sec

Therefore Time taken to pass the man

=(50  x3 /50) sec= 30 sec.

1/3 of 1/4 of x = 15

x/12 = 15

3/10 x = 15X 3/10 X 12 = 54

As the 3 digit number must be a multiple of 5, it must have 5 in its units place

Ex: xy5. X and Y can be any of the remaining 5 digits(2,3,6,7,9).

These remaining 5 digits can have 5p2 permutations ( P- because the arrangement is important). 5p2 =20.

That gives 20 possible arrangements of the 5 digits. 

Sum of the present ages of husband, wife and child = (27 x 3 + 3 x 3) years = 90 years.

Sum of the present ages of wife and child = (20 x 2 + 5 x 2) years = 50 years.

Husband's present age = (90 - 50) years = 40 years.

Sum of the present ages of husband, wife and child = (27 x 3 + 3 x 3) years = 90 years.

Sum of the present ages of wife and child = (20 x 2 + 5 x 2) years = 50 years.

Husband's present age = (90 - 50) years = 40 years.

Sum of the present ages of husband, wife and child = (27 x 3 + 3 x 3) years = 90 years.

Sum of the present ages of wife and child = (20 x 2 + 5 x 2) years = 50 years.

Husband's present 

Father's age = 4 X Son's age

Father's age + 8 years = 2.5 (Son's age + 8 years)

If we subtract,

- 8 years = 1.5 Son's age -20 years

Son's age = 8 years

Father's age = 32 years

After further 8 years (total 16 years),

Father's age = 48

Son's age = 24

All the numbers picked by Ralph are square numbers.

the only square number in the options is 1600  

By rearranging LNGEDNA we get 'ENGLAND'
