Answer 1

$\green{ \underline \bold{total \: money \: of \: mango \: :}} \\ \tt : \implies (1 .60) \times n + 0.8 = mango \\ \orange{ \underline \bold{total \: money \: of \: apple :}} \\ \tt : \implies \: (0.7) \times (n + 10) + 0.10 = apple \\ \blue{ \underline \bold{let \: see :}} \\ \tt : \implies \: 1.60n + 0.8 = 0.7n + 7 + 0.1 \\ \tt : \implies0.9 = 6.3 \\ \tt : \implies \: n = 6.3 \div 0.9 = \frac{63}{7} = 7 \\ \\ \red{ \underline \bold{now :}} \\ \tt : \implies \: m = 1.6 \times 7 + 0.8 = 11.2 + 0.8 \\ \tt : \implies12rs \: answer$

Answer 2

Answer:

totalmoneyofmango:

:⟹(1.60)×n+0.8=mango

totalmoneyofapple:

:⟹(0.7)×(n+10)+0.10=apple

letsee:

:⟹1.60n+0.8=0.7n+7+0.1

:⟹0.9=6.3

:⟹n=6.3÷0.9=

7

63

=7

now:

:⟹m=1.6×7+0.8=11.2+0.8
