ছোট সংখ্যাটি খুঁজুন যার যোগফল ১৪৭ এবং একটি অন্যটির ০.৩৭৫ গুন থেকে ৪ বড়।
To solve this problem, let's analyze it step-by-step:

Step-1: Let, two numbers are X and Y, where X > Y

Step-2: Sum of these numbers is 147. So, X+Y=147

Step-3: According to the question if we multiply the larger number by 0.375 then add 4 more than it will be equal to the smaller number. So, Y = 0.375*X + 4

Step-4: We have to find the smaller number (Y).

Step-5: Now, X + Y = 147
                     ->X = 147-Y   
And from step-3 we find, Y = 0.375*X + 4
       -> Y = 0.375*(147-Y) + 4
       -> Y = 0.375*147 – 0.375*Y + 4
       -> Y = 55.125 – 0.375*Y + 4
       -> Y = 59.125 – 0.375*Y 
       -> Y + 0.375*Y = 59.125 
       -> 1.375*Y = 59.125
       -> Y = 59.125/1.375
       -> Y = 43
So, the smaller number is 43.

#Answer: 43
