So we don't know both of their age but we do know that Jessica is 4 year younger so let make x stand for Jennifer age and n is for jessica so our equation needs to be n + 10 = 8 + 2n subtract n from both sides so now we have 10 = 8 + n then subtract 8 from both sides so now we have 10 - 8 = n so jessica is 2 but now we need to find Jennifer age by adding 4 to 2 = 6
jessica is 2 and Jennifer is 6
Step-by-step explanation:
So, cost of 6.5 kg of apples is Rs. 520 and we need to find cost of one kg apples.
<h2>It can be done just by applying Unitary Method!</h2>
So,
6.5 kg -- Rs. 520
1 kg -- Rs.(520/6.5) = Rs.80
<h3>So, cost of 1 kg apples is Rs.80.</h3>
That means he had 400 or 4000mm
