Answer:
he Present age of Prisca will be 4 years .
Step-by-step explanation:
Given as :
The ratio of present age of Prisca and Ashmaal = 2 : 3
Let The present age of Prisca = 2 x years
Let The present age of Ashmaal = 3 x years
After 4 years , the ratio of present age = 4 : 5
i.e =
Or, 5 × (2 x + 4) = 4 × (3 x + 4)
Or, 10 x + 20 = 12 x + 16
Or, 12 x - 10 x = 20 - 16
Or, 2 x = 4
∴ x =
i.e x = 2
So, The present age of Prisca = 2 x = 2 × 2 = 4 years
And The present age of Ashmaal = 3 x = 3 × 2 = 6 years
Hence, The Present age of Prisca will be 4 years . Answer

Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
