Then, z + 120% of z = 550.
⟹ z + | 120 | z = 550 |
100 |
⟹ | 11 | z = 550 |
5 |
⟹ z = | ❨ | 550 x 5 | ❩ = 250. |
11 |
U ? A = {a, b, c, d, e, f} ? {a, b, c} = {a, b, c, d, e, f} = U
(U ? A)? = ?.
Sunil's income is less than Mukul's = [(10 / (100 + 10)] × 100 %
= ( 1000 / 110 )%
= 9.09 %
So, 39 is wrong.
So, 33 is wrong. It must be 35
∴ x = 7.
So, 40 is wrong.
