Brain training is important at any age, but it is especially important for children, teenagers and the elderly. It doesn’t have to be solving difficult tasks for long hours, but regularity is extremely important. See how to solve the fruit math puzzle for seniors.

Fruit math puzzle for seniors. How to solve it?

Of course, the fruit here is just a nice change of scenery, because it’s actually an equation with three unknowns. We can easily give “b” instead of banana, “j” instead of strawberry or “p” instead of orange. Similarly, we can replace these symbols with classical, mathematical x, y, z or a, b, c, but the aesthetic values ​​prevail over the colorful fruits.

However, it is worth knowing how to approach the solution of this type of task. The most efficient method is to calculate one variable, then substitute the result into the remaining equations and perform subsequent calculations.

At first glance, you can see that the easiest will be to calculate the value of the orange, so Mr. In this case it will 12 – p = p We add p to both sides and get 2p = 12, that is p = 6. Thanks to this, we can easily proceed to the calculation of the expression in the third line.

Instead of banana, we put b and we have the following equation to calculate b ÷ 6 = 6. We multiply both sides by the number 6 and get b = 36.

Thanks to this, we can calculate the very first equation, in which only the strawberry remains unknown, i.e. In this case, it will be: 36 + 6 × j = 66.

This is where the biggest problem can appear that will affect the solution. Some people might first want to “flip” the numbers from left to right and get the equation j = 24. However, in thinking this way, we forget the sign of the multiplication between 6 and j.

A more unambiguous writing of this equation would be 36 + 6j = 66. In that case, after shortening, we get the expression 6j = 30, so j = 5. Thanks to this, we solved the whole problem under the banana and under the orange — 6 and under the strawberry — 5.
